🦈 Daily Shark Fact: 🦈

Speartooth Sharks are a rare species of river shark, one of the rarest animals on earth actually. Scientists estimate that only around 200 of these interesting sharks, are left in the world.

shark of the day: speartooth shark, glyphis glyphis

------------------------------------------------------------

the speartooth shark is a rare species of diadromous shark, one of only a few types of shark capable of surviving in both freshwater and saltwater. they genrally grow to be around 2.5 metres ~(8.5 ft) long but may grow larger. speartooth sharks are found in fresh and saltwater around rivers in northern australia and southern papua new guinea. they feed on fresh and saltwater fish

[wachinyeya]

Charles Darwin University (CDU) researchers and First Nations Yugul Mangi Rangers have discovered a new population of a rare and threatened shark species in the Northern Territory's Roper River.

The Speartooth Shark or Glyphis glyphis is a rare species of river shark that inhabits only a small number of tropical rivers and adjacent marine waters in northern Australia and southern Papua New Guinea.

The species is currently listed as Critically Endangered under Australia's national environmental legislation, with a very small population and a restricted geographic range.

The speartooth shark is one of the rarest sharks on earth. They are so rare that they only live in the waters of Australia and New Guinea with a population of less than 2,500!! They're a critically endangered species.

Was that more than one fact? I dunno but enjoy!!

Speartooth Shark - is a member of the Requiem sharks family. It inhabits coastal marine waters and tidal reaches of large tropical rivers in northern Australia and New Guinea. It feeds primarily on fish. It is a protected species in Australia and is also considered a vulnerable species. It can reach a maximum length of 100 cm (39. 4 inches). https://www.redbubble.com/shop/ap/165287413

There are four types of coral reefs!! Fringing, Barrier, Atoll and patch!! Fringing reefs are reefs that directly emerge from the shoreline, lacking a distinct deep water channel or lagoon between the reef and the adjacent land. However, there may exist shallow areas of sand bottom between the beach and the inner edge where coral growth begins.

When a fringing reef extends its growth vertically from a volcanic island that has completely subsided beneath the sea level, it gives rise to a unique coral structure known as an atoll. Atolls typically exhibit a circular or oval shape, encircling an open central lagoon, The formation of an atoll begins with the initial growth of a fringing reef around the perimeter of a volcanic island.

Over time, as the volcanic island gradually sinks, the coral continues to grow upward, maintaining its position at or near the surface of the water. As the island disappears beneath the waves, only the circular or oval-shaped coral reef remains, forming a complete ring or rim with no landmass in the center. Atolls are basically just volcanic lagoon reefs which I find the coooollesst!!

Barrier reefs, similar to fringing reefs, run parallel to shorelines; however, they are distinct in that they are separated from the land by a considerable expanse of water. This creates a lagoon, typically deep, between the reef and the shoreline.

While less common compared to fringing reefs or atolls, examples of barrier reefs can be found in both the tropical Atlantic and Pacific regions. Barrier reefs are characterized by their formation in open water, initially starting at the offshore edge and subsequently growing parallel to or towards the coast. Unlike fringing reefs, barrier reefs possess deeper channels or lagoons that separate them from the mainland. Their formation is not immediate adjacent to the shoreline, but rather occurs through the evolution of the surrounding substrate or changes in sea-level.

Patch reefs are clusters of coral formations that are physically separated by sandy rings, yet closely situated to one another. They are commonly found in shallow lagoons within larger collective reefs or atolls.

There’s also bleached reefs but they’re pretty new and it’s due to climate change and water rising. I think the ecosystem becomes different and the algae eats on the bacteria that’s on the coral and that’s why they loose color but I could be wrong!! This is Pavi signing off and I’ve hoped you enjoyed this lecture about coral reefs!! + bonus you get shark ramble

There critically endangered which is sad because they're so cute. They're found in both salt and freshwater which is rare!! And only fish of the euryhaline species so your salmon, eels, flounder, and three more species can do?? I'm not sure about sharks but considering there are only 500 now I'd count that as special.

The speartooth shark is found in New Guinea and northern Australia in the bottom of rivers (almost like its in the name). Their habittat is shrinking because illegal gillnetting ( hook and line fishing), commercial and recreational fishing along with just pollution in general.

There are about 2000 left which is sad and I hate it here like just let the sharks live. People say that sharks are dangerous when it's dolphins who are they're literally horrible creatures. The only reason why sharks bite is because they're curious and can't reach out with their fins. Their nose and teeth are how they like...idk it's their sensory. It's how they view the world even with eyes they aren't always the best so they bite.

that's actually super cool!! i'm like- terrified of the ocean but for some reason sharks have never given me the ick that's so nice to know about them (not the deaths that's despicable and based on the little i know, "shark attacks" aren't as common as portrayed and they rlly aren't attacks they're just the sharkies defending themselves or something similar :c)

don't dolphins like. rape people? idk if that's true but i've heard it a lot and it freaks me out, esp cuz they're seen as super smart and cute and social so not a lot of people are taught about that aspect of them and instead demonize sharks for just living :(

attols sound so interesting!! sorry i probably sound like a broken record i promise i'm genuinely interested - by volcanic does that mean they help out their environment or not? :0 i wanna do some research now omgg but thassalophobia or however you spell it sux hh

YES! Okay so Great white sharks can change their body temperature, all sharks have no bones since it’s only cartilage, whale sharks are the length of a school bus, the speartooth shark is one of the rarest sharks on earth, and Greenland sharks can reach up to live for 250(potentially 500) years!

hello fellow homosexual, would you like shark facts on this fine day? :)

sure! sharks are fun! i built a robot shark once!

My March Mammal Madness round 2 portraits. I wanted to give them their own additional post, to highlight their special theme of “portraits with interesting framing devices:. With the spotted skunk piece, I decided I wanted to focus more on detailed portraits, but still keep them visually interesting. Some of these were made with less time than I’d like, but I made it a point to always keep to the theme.

California Condor

Red Panda

Red-footed Booby

Trumpeter Swan

Speartooth Shark

European Badger

Pygmy Spotted Skunk

Western Tree Hyrax

The ones I’m most proud of are the condor, the swan, and the hyrax. Tell me which is your favorite?

With the other half of the peasant retirement fund, consider purchasing one of the few freshwater tolerant species of shark.

Options include the Bull Shark, Ganges Shark, Speartooth Shark, and Borneo River Shark.

Turns out that there's like. Different types of water? There's this stuff called "saltwater" which is the kind of water you find in the oceans, and then there's stuff called "freshwater" which is the kind you find in lakes and ponds. And um basically fish that live in one type of water don't last very long in the other.

All this to say that I bought a shark for my moat and it lived less than a day. What the frick. I've kept carnival goldfish in bowls that lived longer than that. And they didn't cost half of the Peasant Retirement Fund.

a collection of shark facts, since i just watched a documentary

- bull sharks are the only sharks that can move between freshwater and saltwater

- sand tiger sharks have two wombs, and only reproduce once every 2 years. baby sand tigers will eat each other in the womb!

- speartooth sharks are the rarest shark in the world

- port jackson sharks one of the friendliest sharks in the world, and are one of the few sharks that lay eggs instead of live birth

- there is a shark species named porbeagle. i don't have any facts about them i just really like the name. poor beagles :)

- tiger sharks near hawai'i like to hang out around maui during winter, particularly olowalu. this is because the reef is a prime breeding and birthing area for them!

- epaulette sharks can walk! they slow their breathing & heartrate and shut off parts of their brains, and can be out of water for up to an hour! they're the only shark that can do it!

- whitetip sharks used to be super abundant, but have had a 98% population decrease in the last 60 years. this is very very sad.

- tiger sharks are WILDLY unpredictable in their movements, and scientists believe that at least part of the reason why is because they're ambush predators! they gotta rely on surprise, and being unpredictable means they're even more surprising!

- sharks can taste the difference between sweet, salty, sour, & bitter flavours!

- sharks are (of course) apex predators- but more than that, they're a keystone species, which means that without them, the prey population will spiral out of control and could destroy ocean ecosystems. this is bad. protect sharks!

- in fact, without sharks, sea turtles will chow down on sea grass. sea grass traps carbon dioxide, and if the turtles eat it all (and without sharks to stop them, they will), more and more carbon dioxide will get released into the air, accelerating global warming. so if you wanna protect the turtles, you gotta protect the sharks too!

- nurse sharks like to cuddle!!!! they pile on top of each other while they rest and it's so cute

- it's been proven that sharks have personalities!

- there are nine known species of hammerhead sharks! the biggest (the great hammerhead) can grow up to 20ft/6m, and the smallest (the bonnethead) can grow up to 5ft/1.5m!

- a newborn dwarf lanternshark is about the length of your pinkie finger!

- meanwhile, a newborn great white is about 5ft/1.5m long!

- there were only 57 unprovoked shark attacks world wide in 2020, only 10 of which were fatal. in 2018, there were only 66 world wide, and only 4 that were fatal.

- sharks almost always bite people thinking they're seals or sea lions rather than humans, and rarely go back for a second bite!

- a person is actually more likely to be struck by lightning than bit by a shark!

- the fastest known shark species in the world- the shortfin mako shark- can reach 60 miles/97 km an hour!

let me know your favourite shark, and any fun facts you know about them!
