Heroes with the fish tails, sharky power!

MASTERPOST

(Individuals pics and yapping under the cut ^^)

HEHE THE HYPERFIXATION CONTINUES this took my several hours bc i draw so slowly and dont realize it so that was great but i really like them ^^

Raph is a great white just bc I thought it fit, Mike is a leopard shark bc of spots and bc little, Leo is a pelagic thresher bc he’s a speedy boy, and Donnie is a shortfin mako bc they’re very smart!

I was trying to find an equivalent to sharks for Donnie and his soft shell but i couldn’t think of a species specific thing so I’ve decided that when they were rescued my Lou, he got burn damage to his snout where his sensing organs are and since sharks rely on that organ a lot due to they’re poor eyesight, he can struggle in seeing things. Technically they all have awful eyesight but the others can sense the electro magnetic fields and whatever so they’re good. Hence Don needs glasses and just still struggles beyond that.

Ummmmm yeah so they all have tails and dorsal fins and little fins on their tails. They each have sets of gills on their necks and rib area while also having lungs. They can breathe underwater then, they just have to keep their mouths closed. I also think their lair situation would be the same with more pools for them since they do like water but their human characteristics don’t make them dependent. Maybe just water lovers and avid moisturizers.

OKAY IF ANYONE WANTS TO SEND ME AN ASK ABOUT THIS ID BE HAPPY TO TALK BUT YOU KNOW UP TO YOU TEEHEEHEEHEE I NEED TO EAT NOW BYEEEEEEE

ok so like many people on here i'm very autistic abt fish (and other animals) so i'm gonna just start posting my notes app infodumps on the fish autism website

Definitely one of the goofiest sharks out there, i've gone on record as claiming the pelagic thresher (Alopias pelagicus) as my favorite shark. Threshers are known for their extremely long tail, which is used to help catch prey. The thresher uses its tail like a whip to stun groups of small fish. Points for creativity!

The pelagic thresher can be identified by dark patches of skin around the base of its fins and smaller eyes than its relatives. Perosnally, I would describe the species as looking like its mom just left it in line at the cash register to go grab something she forgot. Delightful lil guys!

Fish of the Day

Today's fish of the day is the the Pelagic thresher shark!

The pelagic thresher, also known as the pacific common thresher shark, scientific name Alopias pelagicus, is a common thresher shark. Found along the tropical and subtropical waters in the Pacific and Indian ocean, stretching from South Africa to The West Coast of America. Like other thresher sharks, the pelagic thresher inhabits the open ocean, occasionally coming close to the continental shelf near coral reefs, and seamounts. Seasonally, they migrate North and South, to follow warmer waters. Pelagic threshers are the smallest species of thresher shark, and despite being visually similar to their relatives they can be differentiated by the dark pigment above the pectoral fins and the rounded fin tips.Similar to other threshers, the teeth are smooth and small, with 20-22 teeth per jaw, curved inward to trap prey inside their mouth.

Due to their medium size, the pelagic thresher is predated on by many larger predators. Primarily larger sharks, orcas, and other toothed whales that share an area. They are known to have tapeworm parasites and copepods in the skin. This leads to the symbiotic relationship with cleaner wrasses, who eat their parasites. The pelagic thresher's diet consists of small prey along the mesopelagic zone, primarily lightfishes, barracudas, flying fishes, herrings, squids, and mackerels. This keeps them from competing with other oceanic predators in their size range, such as tuna, billfish, and other sharks. They hunt similar to other thrasher sharks, by swimming tight circles around a school of prey, until they condense. Then, striking with the upper caudal fin tip lobe of the tail to stun. This long tail is often the cause for plegic threshers getting hooked as bycatch for other fishing efforts, specifically having issues with longlines.  Although several commercial fisheries go out of their way to hunt for plegic threshers, leading to their status as endangered.

Just like all other mackerel sharks, the pelagic thresher shark is ovoviviparous, meaning they have young kept in eggs within the mother, and when they hatch, they are born live. Similar to other thresher sharks , the pelagic thresher gives birth to two pups at a time, one per each uterus. They have no defined breeding season and the gestation period is unknown, but assumed to be similar to the year gestation period of common threshers. Pups are born surprisingly large, at about 5 feet in length. As compared to the sexually mature adult size of about 10 feet, the largest recorded being around 11feet. Maturity is reached at around 9 feet in length, which is usually around the 8th or 9th year in females, and around 7-8 years in males. Their lifespan is about 28 years in females, possibly longer, whereas male threshers get the short stick, living only 17 years in comparison.

Have a wonderful day, everyone!

Thresher Shark! Specifically a Pelagic thresher in this painting but there are three species of Thresher. Each has a very elongated part of their tail which can be used to stun prey to eat.

I LOVE YOU GREAT AQUA CAVEEEE, and i love you pelagic thresher too!

[sharklovingcriminals]

Bro they do even cooler hunting where they approach some prey angled slightly downwards, bring their pectoral fins (the ones which are like shark arms) forward to stop their momentum, but their tail still keeps its momentum and it flips over the shark's head and cracks like a whip into some fish, which is literally fucking sick.

Have you done any fun facts about thresher sharks? Love ur blog!!! :3

Ahh that makes me so happy!! This blog is still really new and I was mostly just expecting it to be me talking to myself, so it makes me smile to know you like it too :)

I haven't had a chance to talk about thresher sharks yet, but aren't they great? All three species of threshers are just peak sharks, really - they're cool, they got big silly eyes, they always look like they just nervously asked you to prom and weren't expecting you to say yes and now they don't know what to do

How about some fun facts about the pelagic thresher? They're actually the smallest of the three thresher species (not that any of them are super big, really), and it's easy enough to confuse them with the common Atlantic thresher that we actually can't be confident we know what their range looks like! Their big eyes are a hallmark of the species (they make them look so cute and silly), and they actually decrease in size relative to the shark's body with age, so you can guesstimate a thresher's age as juveniles will have very big peepers. We can't be certain at this stage, but current research indicates that, unlike the common thresher, the pelagic thresher probably isn't warm-blooded, which has interesting implications for how even sharks within the same genus have evolved to thermoregulate differently.

Of course, one of the coolest things about pelagic threshers is their hunting strategies! These sharks literally evolved to herd fish around and then slap them with those long tails.

I keep seeing these cute “guess the shark species” slideshows l on tiktok, but they always show a pelagic thresher shark and just call it a “thresher shark,” so I realized not a lot of people might know there are three species of thresher shark. I’m going to introduce you to all of them and give you some certified marine biologist (tm) tips and tricks to notice species-specific features to look for once you see the long tail that indicates it’s in Alopiidae (since even google images messes it up sometimes).

This is a pelagic thresher shark (Alopias pelagicus). It is the smallest of the three species, and usually the one everyone thinks of. Some of the most distinguishing features to me are the slender body shape, a smooth head with no noticeable ridge, and eyes that are still somewhat large, but not noticeably so. But the most important distinguisher to me is its coloration, the white on the shark’s ventral side forms a border with the grey on it’s dorsal side, and this border goes *under* the pectoral fins, not *over*. They can be found to at least 150 m.

The common thresher shark (Alopias vulpinus) is the one that’s the most annoying to find on google images, because half the images are of the pelagic thresher. It is the largest species of thresher shark. As you can clearly see, these guys are a bit chunkier and also don’t have a noticeably large eye, and they have a smooth head that lacks a noticeable ridge. But the most important distinguisher for these guys is also related to their coloring. As you can kind of see in this photo, the border between the white of the ventral side and grey of the dorsal side goes well above the pectoral fin, so they have a spot of white that goes *above* their fin. This is the easiest way to distinguish them from pelagic thresher sharks, since you might see them within the same size range, so going off of body shape and size alone isn’t the most reliable.

And lastly, we have the bigeye thresher shark (Alopias superciliosus), so hopefully now it’s clear why I was harping on the eyes so much for the last two. Their gigantic uwu eyes are definitely a distinguishing feature, but the most prominent feature you want to look for during identification is the large ridge between the top of their head and their body. It’s super noticeable in person as well, and is not a feature shared by the other two sharks. These are the most easily distinguishable from the other two, and can be found to a depth of up to 723 m.

All thresher sharks are ovoviparous, so they give live birth! And they’re all cutie patooties who deserve to be appreciated.

why don't you [look at pictures of pelagic thresher sharks swimming over the abyss] and maybe you'll feel better

Okay I finally got everything decided for the merfolk Straw Hats! I’ll be tagging everything related to this as ‘merfolk au’.

Luffy is a bull shark. Hear me out on this one. This shark is a voracious eater and an extremely strong predator. They’re also capable of surviving in freshwater for surprisingly long periods of time, which I think compliments Luffy’s adventurous nature. They also sometimes fight crocodiles, which I just happened to find funny.

For Zoro, I think the green moray eel would be fitting. I know swordfish is the obvious choice, but I wanted to do something different. These fish are aggressive and vicious fighters. Also, they don’t clean themselves and instead rely on other fish to clean them, which is very Zoro like in my humble opinion.

Nami is a flame angelfish. A gorgeous fish that is known for having a temper. They’re also expensive in the fishkeeping hobby, which is very on brand for Nami.

Usopp is an indo-pacific sailfish. Between them being one of the fastest fish in the ocean and their long nose, it’s a perfect fit.

Sanji is a pelagic thresher shark, a fierce fighter that uses its tail as its main weapon. They’re also very athletic, capable of swimming at high speeds and breeching out of the water.

Chopper is a reindeer that ate the mer-mer fruit and became a blue spotted pufferfish merman. I chose this one because the defense mechanism fits his scaredy cat personality, and also because this fish doesn’t get along with members of its own species very well.  

Robin is a mimic octopus. They can change colors, as well as alter the length and texture of their legs, which I think works well with her devil fruit ability. They’re also masters at hiding which suits her well.

Franky is a peacock mantis shrimp. These guys are very intelligent, and their strong armor and unique attacks suit Franky’s cyborg status nicely. Their colorful appearance and blue head is also fitting to such a colorful and boisterous character.

Heya boss,

I'm evil requesting you do a big eye thresher, requesting it evil style, maliciously, if you'd be ever so kind

shark of the day: bigeye thresher shark, alopias superciliosus

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

the bigeye thresher shark is a large species of mackerel shark identifiable by their characteristic long tails and large eyes. they can grow to up to around 4.8 metres(~16 ft), of which nearly half is the length of the upper lobe of the caudal fin. bigeye thresher sharks are found in deeper pelagic tropical and subtropical waters around the globe. they feed primarily on large pelagic bony fish as well as cephalopods and crustaceans, using their long whiplike tails to stun prey. of the thresher sharks, the bigeye thresher has the shortest tail-to-body length ratio.

SHARK FACT!

Newborn pelagic thresher sharks, Alopias pelagicus, can be as long as almost half the length of the mother. Most of this is down to those tails which can account for 50% of the total length of the shark, but it's still long.

There are three currently described extant thresher shark species (Alopias spp.), smallest is the pelagic thresher A. pelagicus, the bigeye thresher A. superciliosus is in the middle size wise, and the common thresher A. vulpinus are the largest. All three are ovoviviparous, which means that although the babies develop in eggs, these eggs are never layed and the sharks give birth to live young.
