what's your take on pacman/ornate horned frogs?

Okay so Ceratophrys themselves are pretty great (all round frogs are good frogs), but have you heard of PROceratophrys?

[source]

Some species are just like Ceratophrys, but with eighteen times the eyebrow.

Like, honestly?

[source]

Whose idea was this?

Interestingly, even though they're called PROceratophrys, they're not even in the same family (Odontophrynidae versus Ceratophryidae), and are separated by over 60 million years. Proceratophrys are more closely related to bufonid toads and hylid tree frogs than they are to Ceratophryidae!

Sometimes taxonomy is just dumb that way.

In the world of amphibians, few creatures capture the imagination quite like the horned frog. Known for their distinctive appearance and unique behaviors, horned frogs, belonging to the Ceratophryidae family, are fascinating inhabitants of various ecosystems. This article will explore the characteristics, habitats, and intriguing features that make horned frogs a captivating subject in the realm of amphibians.

I. Introduction to Horned Frogs

Horned frogs, also referred to as pacman frogs due to their resemblance to the iconic video game character, belong to the Ceratophryidae family. These frogs are native to South America and have gained popularity in the exotic pet trade due to their distinctive appearance and intriguing behaviors horned frogs cup.

II. Physical Characteristics: A Cloak of Camouflage

One of the most striking features of horned frogs is their appearance. Their bodies are broad and flat, resembling a leaf or a stone, providing excellent camouflage in their natural habitats. Explore the variations in colors and patterns that different species of horned frogs exhibit, ranging from vibrant greens to earthy browns.

III. Horned Protrusions: Defensive Adaptations

True to their name, horned frogs possess bony, pointed protrusions above their eyes, resembling horns. While these may look intimidating, their primary function is camouflage. However, when threatened, horned frogs can arch their bodies and raise these "horns," adopting a defensive posture to deter potential predators.

IV. Diverse Species: An Array of Horned Frog Varieties

The world of horned frogs is diverse, with several species exhibiting unique characteristics. Explore different species, such as the Argentine horned frog (Ceratophrys ornata), Cranwell's horned frog (Ceratophrys cranwelli), and the Fantasy horned frog (Ceratophrys hylandersi), each with its own set of colors and patterns.

V. Habitats: From Tropical Forests to Grasslands

Horned frogs inhabit a range of ecosystems, from tropical rainforests to grasslands and savannas. We'll delve into the specific environmental conditions preferred by different species, shedding light on how these frogs have adapted to diverse habitats.

VI. Dietary Habits: Ambush Predators of the Amphibian World

Horned frogs are renowned for their ambush predation tactics. Their diet consists mainly of insects, small mammals, and even other frogs. Explore how their patient waiting, aided by their excellent camouflage, allows them to strike swiftly and consume prey nearly their own size.

VII. Reproduction: Unique Breeding Strategies

The breeding habits of horned frogs are equally fascinating. We'll discuss their unique reproductive strategies, including the male's role in guarding the eggs and tadpoles, as well as the intriguing parental care exhibited by some species.

VIII. Life in Captivity: Horned Frogs as Exotic Pets

Due to their unique appearance and relatively straightforward care requirements, horned frogs have become popular choices in the exotic pet trade. Learn about the considerations and responsibilities involved in keeping horned frogs as pets, from creating a suitable habitat to understanding their dietary needs.

IX. Conservation Status: Challenges and Threats

While not all horned frog species are currently classified as endangered, some face threats due to habitat loss and the pet trade. Explore the conservation status of various horned frog species and the efforts being made to preserve their natural habitats.

X. Educational Importance: Studying Horned Frogs in Scientific Research

Beyond their roles in the pet trade, horned frogs contribute to scientific research. We'll highlight how these amphibians are valuable subjects in studies ranging from ecology to physiology, offering insights into broader aspects of amphibian biology.

XI. Cultural Significance: Folklore and Symbolism

In some cultures, horned frogs hold symbolic significance. Discover the folklore and cultural representations associated with these unique amphibians, exploring how they have become characters in stories and legends.

XII. Conclusion: Horned Frogs - Nature's Masters of Stealth

In conclusion, horned frogs stand out as remarkable creatures in the world of amphibians. Their unique appearance, ambush predation tactics, and adaptability to diverse environments make them both captivating subjects for enthusiasts and valuable contributors to scientific understanding.

A particularly large species of prehistoric frog described in 2008. Common names assigned by the popular media include devil frog, devil toad, and the frog from hell. Fossils of Beelzebufo have been recovered from strata of the Maevarano Formation in Madagascar, dating to the late Cretaceous period, its assumed to have lived 66-70 million years ago. It is considered to be closely related to Baurubatrachus from the Late Cretaceous of Brazil, with both possibly being close relatives, though not members of, the extant South American frog family Ceratophryidae.

Honk for the Amazon Horned Frog

The Amazon horned frog, or the Surinam horned frog (Ceratophrys cornuta) is a medium-sized species of frog found in the tropical forests of South America. They tend to be wide and bulky, but only grow to be about 20cm in length and weigh 0.5kg. Color schemes can range from tan to green to brown, and this frog blends in very well with the leaf litter on the forest floor. The Amazon horned frog’s name comes from two horn-like protrusions over the eyes, although these are more likely meant to break up the frog’s silhouette than to be used for fighting. This species is also sometimes mistaken for a toad due to the bumps over its skin.

Like all frogs and toads, C. cornuta begins its life as an egg. After a male attracts a female by calling and the two mate, the male helps deposit the fertilized eggs onto the female’s back. The usual clutch size ranges from 300-600 eggs. The female then searches for an appropriate place-- usually an ephemeral pool-- for the eggs to develop into tadpoles, a process that takes anywhere from 3 to 25 days after being fertilized. Tadpoles are highly aggressive and will fight each other as they develop. It takes three months for tadpoles to grow into fully-formed frogs, although they do not become sexually mature for another 3 or 4 years.

In their day-to-day life, Surinam horned frog spends its time hiding in leaf litter or under fallen logs. It is an ambush predator, to which its appearance lends itself well. It’s predation actually makes it one of the most distinguished frogs, as they have one of the largest mouth-width to body length ratios. This exceptionally large mouth enables them to consume a wide variety of prey, including mice, fish, frogs, lizards, and tadpoles of their own species. Common predators consist of birds and snakes. Against each other, Amazon horned frogs are incredibly violent and will attack each other with their sharp teeth. They will also use those sharp teeth against predators or perceived threats.

Conservation status: Listed as Least Concern by the IUCN; however, they are currently threatened by heavy habitat loss and capture for the pet trade.

Ceratophrys calcarata by Andrés Acosta

[itsfrogtober]

frog of the day :)

Ceratophrys ornata, Common names: Argentine pacman frog, ornate horned frog, Argentine wide-mouthed frog

Habitat: Swamps, bogs and other shallow bodies of water. Near grassland areas.

Found in: South America and Africa. Most common in Brazil, Uruguay and Argentina.

Fun fact(s): They are the most common species of pacman frog, a very unique and interesting frog family!

They are large frogs, growing 5 to 7 inches in length, on top of this, pacman frogs are characterized for being very wide as well, making this guy even bigger.

Being pacman frogs, they are carnivorous frogs, who go after some pretty large prey. Pacman frogs are known to eat anything that can fit in their, very large for a frog, mouths. In the wild, an Argentine pacman frog’s diet would consist mainly of mice, small reptiles, spiders and locusts. 

Pacman frogs, including the Argentine pacman frog, are popular as pets. The Argentine pacman frog’s diet in the wild is somewhat hard to recreate, but pets are usually fed large locusts and crickets, and sometimes live fish. 

Their tadpoles can make distress calls, and they were the first species of frog recorded to be able to do this

The fossil record and phylogeny of South American horned frogs (Anura, Ceratophryidae)

Raúl Orencio Gómez & Guillermo Fidel Turazzini

Abstract

South American horned frogs (Ceratophryidae), with their large heads, wide gapes and fang-like teeth, are among the most charismatic, best-known and well-studied neobatrachian anurans. The family comprises 12 extant species with hyperossified skulls and has a relatively rich fossil record, particularly in the Pampas, which dates back to the late Miocene. 

However, several records have been overlooked in recent summaries, and many taxonomic assignments remain indeterminate or are questionable and have yet to be tested within a quantitative phylogenetic framework. 

Here we provide a complete up-to-date survey of the palaeontological record of Ceratophryidae, including some remarkable new records. We also tested their systematic position through comprehensive phylogenetic analyses based on osteological data, providing several synapomorphies for all relevant nodes. 

Finally, we discuss these integrated data in relation to divergence time estimates, and propose a set of fossil calibrations that provide hard minimum bounds for crown-group Ceratophryidae and the subclades within it, and illuminate the acquisition of polyploidy within the group.

How Can We Do Better By Pacman Frogs?

Pacman frogs (genus Ceratophrys) are one of the most common pet frogs, and for good reason! They’re large, personable frogs that come in a wide variety of morphs and can live up to 10 years. There are eight species in the genus, though only three are common in captivity (C. cranwelli, C. ornata, C. cornuta), as well as a hybrid of C. cranwelli and C. cornuta usually labelled as a “fantasy pacman frog.” Occasionally you may see some of the other species for sale, but not nearly as often. This article focuses on the three most common species of pacman frog, excluding the hybrids.

This article is not intended to be used as a care sheet. Please do further research of your own to figure out the best way to care for your pet pacman frog. 

Visual differences between the three common pet pacman frogs, plus the ‘fantasy’ hybrid (source)

Unfortunately, in my experience, out of all the common pet frogs, pacman frogs seem to suffer the most from minimalistic husbandry practices. Perhaps this is due to their reputation as ‘pet rocks’- they are nocturnal sit-and-wait predators, so keepers are unlikely to see them out and about during the day. A common sight in pacman frog groups and forums is a bin or tank of no more than 10 gallons, with just some dirt, a heat mat, and a large water dish. But is that really the best we can do for them?

An example of a fairly typical 10 gallon setup for a pacman frog. (source)

In order to answer that question, we’ll first need to delve into their lives in the wild.

In the wild, the ranges of cranwelli, cornuta, and ornata are for the most part separate. Cranwelli is found in the dry chaco region, which includes parts of Argentina, Paraguay, Bolivia, and Brazil. Ornata is found in Argentina and Uruguay, ranging to the coast. Cornuta is found much further north and has the largest range, including Brazil, French Guiana, Suriname, Colombia, Peru, and Bolivia. There’s some possible overlap between cranwelli and ornata in Argentina.

Comparisons from Berkeley Mapper of pacman frog distribution. Orange is range as listed by the IUCN, and the blue dots are amphibiaweb records of collection sites.

Most care sheets and keepers treat these species as interchangeable as far as care requirements, but I’m a little more skeptical. Let’s go species by species through habitat information! 

Ceratophrys cranwelli

The most common species of pacman frog lives in the hot, semiarid Gran Chaco region, which contains mainly dry thorn forests, savannas, and low hardwood forests. Much of the water is seasonal, but there are two permanent rivers. When it’s hot and dry, cranwelli will burrow into the soil and grow a protective layer of skin, then aestivate until the climate becomes more suitable for them again. Soil is primarily sand and clay-based. Average temperatures across the region range from 60-85 F, with average humidity ranging from 50-75%.

Ceratophrys ornata

These guys live in the Pampas region of Argentina, in subtropical grasslands and seasonal wetlands. Vegetation is primarily grasses and shrubs with few trees. Humidity seems to stay around 70-80% on average. The yearly average temperature is just around 65F, with average lows around 55 and average highs around 75. Soil is described as fertile. The frogs are primarily found around the bodies of water where they breed.

Temperature information for three locations in the Pampas region

Ceratophrys cornuta

The third of the common pet pacman frog species is found in the Amazon rainforest and the Amazon basin. The yearly average temperature is around 77 F but can reach up to the 90s during the day and down to the upper 60s/lower 70s at night. Humidity in the amazon rainforest averages 77% in the dry season and 88% in the wet season, according to the WWF. One study on the biology of cornuta cites the forests where they live as either terra firma or inundated forest and the soil asloam mixed with silt and/or clay. Individuals were usually found partially burrowed under leaf litter, with their backs near roots or logs. They mostly moved around during nights when there had been rainfall in the previous 24 hours. 

In my opinion, the differences in habitat between the three species indicates that captive Ceratophrys frogs should be kept in somewhat different conditions in captivity as well. Cornuta would likely do well with plenty of leaf litter to burrow into, and seems to like the highest humidity of the three. Cranwelli seems to need the least humidity, and would likely appreciate some plant or wood cover, such as scrub vegetation. Ornata seems to need higher humidity than cranwelli, but perhaps not as high as cornuta. Their primary vegetation in the wild are grasses, so it would be recommended to mimic that in terraria. The different species may do better at different temperatures as well. I would recommend doing further research on your own on temperatures in their native habitats before deciding what temperature to keep your own pacman frog at.

In general, the small terrariums pacman frogs are typically kept in are inadequate. While a 10 gallon may be fine for growing out a young baby, many of whom are irregular eaters until adulthood, These frogs can grow anywhere from 2-6 inches, possibly more, depending on species and gender. I recommend a minimum of a 20 long (footprint of 360sq in) for male pacman frogs and a 40 breeder (footprint of 640sq in) for female pacman frogs. Of course, you can always go larger- I keep my male ornata in a 40 breeder and I have never felt the space was wasted.

All pacman frogs share some basic needs: enough substrate to burrow all the way into, a large water dish that they can soak their entire body in, cover of some sort be it hides or plants, a heat gradient, and access to UVB.

Most keepers recommend a heat mat taped to the side of the tank for providing supplemental heat. You should never use a heat mat on the bottom of the tank as pacman frogs will burrow to cool themselves down when it gets too hot. Overhead heat would be ideal, and there are many ways to go about that, each with its own pros and cons. Unless your house is particularly cold, your frog should be fine with a nighttime temperature drop down to the mid 60s/lower 70s.

UVB supplementation is controversial in the herp hobby for many species, and pacman frogs are no exception. They may be nocturnal, but that only means they are primarily active at night and  does not preclude them from being exposed to sunlight. I would consider them to be a part of Ferguson Zone 1 as outlined in Ferguson et al. (2010). Animals in this zone are cryptic baskers, typically crepuscular or nocturnal. They would not need high levels of UVB, but appropriate use of a low output UV bulb is unlikely to be harmful provided the frog is able to avoid the light should they choose. I personally use a reptisun T8 5.0, but any light with a similar output used at the manufacturer recommended distance should be safe. Make sure your pacman frog is able to hide from the light if they want to by providing them with hides, plants, pieces of wood, etc.

Ultimately, we can do better by pacman frogs by simply treating them like more than pet rocks. Give them space to move around, do research into the native habitat of the species you own and do your best to mimic it in your terrarium. Feed them a variety of foods - these guys can and do eat almost anything from ants to other frogs and reptiles. Give them more than just dirt and a water dish. Make sure to only purchase captive-bred individuals. These frogs will never race around their tank or be able to be kept happily with other frogs, and you may almost never see them move during the day, but that doesn’t mean they don’t use their space in their own way. 

The way I see it, you can either provide space and enrichment that they might not use, or you can deprive them of space and enrichment that they may benefit from. I think the former is preferable to the latter.

Pacman Frogs

Ceratophrys is a genus of frogs in the family Ceratophryidae comprised of eight species. In captivity, C. cranwelli, C. ornata and C. cornuta are the most popular species. They are also known as South American horned frogs as well as Pacman frogs due to their characteristically round shape and large mouth, thus reminiscent of the video game character Pac-Man.

They are voracious eaters, often eating insects, small mammals (such as mice), fish, other frogs, and small reptiles. A fully grown female Argentine Horned Frog can easily eat a grown rat. These frogs are also known to be cannibalistic, and have been known to eat their mates, even if they are larger than they are. 

Although these frogs can swallow animals almost half their size, they sometimes attempt to eat things larger than they are. A row of sharp bony projections in their upper jaw makes it nearly impossible for them to release prey after taking it in their mouth, in some cases leading to death by choking.

The average lifespan of a Ceratophrys frog in the wild varies between 1 and 4 years, though in captivity and as pets, depending on diet, they may live 6 to 10 years and even longer.

Ornate Pacman Frog Care (Ceratophrys ornata)

Why are pacman frogs so popular? Their large size? Their voracious appetites? The many beautiful morphs they come in? All of the above, and more! Unfortunately, there are downsides to that popularity. Misinformation abounds, and their sit-and-wait lifestyle leads to small, minimalistic keeping. If you haven’t already, I wrote another article (How Can We Do Better By Pacman Frogs?) that addresses some of these misconceptions and more. 

This care sheet is not intended to be used as the sole source for pacman care information, it is merely a guideline. It is important to always do further research of your own to determine the best way to care for your pacman frog. There are eight species of pacman frogs, plus hybrids. This article solely focuses on the ornate pacman frog. If you have a different species of pacman frog, please do further research into your species specifically, as they live in different habitats in the wild and may need different care.

Quick Stats

Species: Ceratophrys ornata Tank Size: 20 long minimum for a male (bigger is ideal), 40g breeder minimum for a female Size: 4.5 inch max for males, 6.5 inch max for females Sociability: must be kept alone, they will eat other frogs Heating: gradient. hot side around 75-85, can be turned off at night Humidity: soaking dish, keep soil damp, 70-80% humidity Lighting: Ferguson Zone 1 Diet: insects, can also be feed pinkie mice and frogs/lizards occasionally Origin: Pampas region of Argentina Lifespan: 10 years on average

The native habitat of the ornate pacman frog is mostly subtropical grasslands and seasonal wetlands. There are few trees, just grasses and shrubs. They can also be found in irrigated cropland and ditches. Humidity stays pretty high around 70-80%. Yearly average temperatures range from 55 to 75 degrees Fahrenheit. 

[source]

Part of the pacman frog appeal is their adorable appearance. A typical ornate is primarily green, with brown spots on the back. Some red may be present as well. The ‘high red’ morph is just about the same, but with increased red coloration. Size of spots, intensity and spread of color, etc are all pretty variable. A male may reach a length of 4.5 inches, while females are larger and may get up to 6.5 inches. Smaller sizes are also common.

Minimum vivarium needs depend on the frog’s gender. Males are several inches smaller and can be kept in a 20 long minimum. The females are larger and would require a 40 breeder. Regardless, bigger is always better! Height is not very important except for as needed to safely provide heat and light, and to provide room for deep substrate. A few broad, sturdy objects that can be climbed will make a good addition and are recommended. 

When it comes to substrate, eco earth, moss, or foam/paper towel are the popular options. However, these are not really the best choices. Paper towels are fine for quarantining, but pacman frogs love to burrow, so after quarantining, frogs should be switched to a loose soil substrate. Organic topsoil, sand, eco earth, leaf litter, clay, and some commercial reptile soils can be used as parts of a nice, quality substrate. Moss is okay, but not as the entire substrate. Substrate should be deep enough for the frog to burrow itself entirely.

Pacman frogs may destroy live plants, but hardy ones may be able to withstand a frog climbing over or burrowing under them. They will also need to tolerate high humidity and damp soil. Pothos, philodendron, spider plants, and dracaena are a few options to look into.

Pacman frogs like high humidity. When the soil gets dry, they may begin aestivation, burrowing deep into the soil and covering themselves in a protective layer of skin. Keep the soil damp, but not soaking, a drainage layer can help prevent this. Hydrating the soil directly may be more effective than misting, but again, you don’t want the soil to be so wet that it turns to mud.

Hides and decor, like for all other herps, are necessary in some form or another. Ornate pacman frogs come from the Pampas region of Argentina, where vegetation is primarily shrubs and grasses. Some amount of cover is important so that your frog can easily hide from the lights if they choose. Their native grassland habitat means that the vivarium does not need to be especially cluttered, but a bit of cover may help them feel more secure.

Supplemental heating should be provided to achieve a gradient. Never use a heat mat on the bottom of the enclosure, as pacman frogs burrow to cool down. Some use heat mats on the side of the enclosure, but this is hardly effective. Heat mats only produce IR-C, the infrared wavelength that penetrates tissue the least, and they only increase the temperature of what they’re touching, not ambient temps. A halogen bulb is your best bet, putting out a combination of IR-A, IR-B, and IR-C most similar to the sun. Deep heat projectors, radiant heat panels, and ceramic heat emitters can also be used, but a halogen bulb is ideal. Unless the room gets very cold, pacman frogs will be just fine with no supplemental heating at night, room temperature will be okay. 

I really recommend providing UV lighting. They are Ferguson Zone 1 animals, meaning they are primarily active at night and will cryptically bask when they need UV. In the wild, they can be found burrowing with their heads poking out during the day. Make sure there is plenty of room to avoid the light, but overall UV lighting is a very good idea.

Never keep a pacman frog with tankmates. They are aggressive and may cannibalize each other if kept together. A pacman frog will eat just about anything that fits in its mouth. This means feeding is very easy. Feeder insects should make up the bulk of the diet, but they’ll happily take small mice, frogs, lizards, or even the occasional feeder fish. Vertebrates should be fed sparingly.

Breeding can be difficult, but not impossible. Many breeders use hormone injections to induce breeding, I recommend against this. Instead, allow your frogs to aestivate and then place them in a rain chamber. Much of the difficulty in breeding frogs results from the natural seasonal cycle not being mimicked. Be warned that pacman frogs are aggressive and an unreceptive female could injure or kill your male. Before attempting to breed, you will definitely want to do further research and speak to people who have bred them before. Breeding is a big responsibility, but it can be very rewarding. Keep in mind that some sections of the pacman frog market are pretty saturated already. Do you have space for the offspring who may not sell right away, or ever?

My male ornate pacman frog’s vivarium. This is a 36x18x12, with topsoil, eco earth, and leaf litter for substrate. The heat source is a 50 watt halogen bulb and the UV light is an Arcadia PureSun mini, which is a good choice if you have a short enclosure like this. For a standard 18” high 40 breeder, you’ll want a higher output UV light. As you can see, live plants are not a necessity- I’m using silk aquarium plants. The wood piece and the log hide also provide cover. More often than not, my pacman frog simply burrows into the substrate with his head visible, out in the open.
