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.

shark list…?

SHARK LIST!!!!!

This is another list that's based mostly off vibes and aesthetic rather than any deep analytical reasons, though I do have some deeper reasons for these choices but let's just focus on vibe for today

RAPH: Tiger shark (Galeocerdo cuvier)

LEO: Common thresher shark (Alopias vulpinus)

DONNIE: Scalloped hammerhead (Sphyrna

lewini)

MIKEY: Leopard shark (Triakis semifasciata)

BONUS

APRIL: Epaulette shark (Hemiscyllium ocellatum)

SPLINTER: Spotted wobbegong (Orectolobus maculatus)

DRAXUM: Horned shark (Heterodontus francisci)

CASEY JONES: Sandbar shark (Carcharhinus plumbeus)

CASEY JR: Blacktip reef shark (Carcharhinus melanopterus)

I promise I wasn't ignoring this ask I was just thinking very deeply about the answer to this list for not only the rise brothers but the direct family ensemble and wanted it to be the best list that I could make (tbh I made this list more for myself and is super based off my personal opinions. I'm a huge shark fan and was really excited to get this ask so I wanted it be a list I was confident in)

#rottmnt #rise of the tmnt #rise mikey #rise leo #rise donnie #rise raph #rise splinter #rise april #rise casey jones #rise casey jr #sharks #tw shark #peachmoths ask tag #fun fact like five of the sharks on this list are sharks i have at my work LMFAO #oh and if you were wondering my top 5 fave sharks list it goes whale shark leopard shark nurse shark bamboo shark and black tip reef shark #i really like carpet sharks can you tell lmfaooooo

On one side we have one big boi and on the other we have the whip tail, who shall win?

Whale Sharks (Rhincodon typus) can possibly have a big regeneration hability, probably even repairing part of its fins, even it's spots can reform after an injured area. The teeth of this shark is completely vestigial, since it plays no role in eating. Not only is the Whale Shark the biggest fish, but it also had the deepest recorded dive of any fish, going down at 1,928 metres (6,325 ft).

Thresher Shark (genus: alopias): The thresher shark is fast and has a very fun big tail, used as a whip to hit prey and stun them. The largest species, Alopias vulpinus, can reach up to 6,1 meters (20ft). They're pretty shy and not a danger to humans. They're fished a lot for the challenge of its speed and strenght.

Hello, fellow animal lover!! Got anything on thresher sharks orrrr nurse sharks. They are two of my favorite sharks!

Hello!! yes!! here you go my friend!!

The Thresher Shark is also known as the Alopias Vulpinus or Fox Shark. Its name comes from the sharks unusually large tail (caudal fin), which is in most cases, as long as the shark itself.

These are very athletic sharks. They are known for slaying their prey with their huge tails and are famous for special jumping techniques and behavior called “breaching” where they jump out of the water and into the air.

-

Nurse Sharks spend their lives around coral reefs and coastal shelves, and most of their hunting takes place right on the ocean floor, where these slow-moving carnivores look for prey in or near the sand. Instead of swimming, they sometimes use their pectoral fins to “walk” across the bottom.

Shark snuggle parties are a thing. By day, the nocturnal nurse shark becomes inactive; for hours on end, it just lies around and pumps water over its gills. Crevices, ledges, and piles of boulders are popular downtime locations for this species. Although the sharks don't socialize on hunting trips, they often recline en masse. Nurse sharks are known to rest communally, with groups of two to 40 individuals piling up on top of each other.

Hope these are satisfactory, I'm a bit under the weather so admittedly they are a bit half assed lol

Anyone who suffers from anxiety has probably made facial expression to this before. This delightful specimen is the thresher shark (Alopias vulpinus) and is also known as the fox shark or whiptail shark. This species reaches lengths of 2.5-7.6 m, although half of this measurement is accounted for by the caudal (tail) fin. This extreme adaptation is imperative to the threshers peculiar hunting strategy, as they are believed to deliver blows from the whip-like tail in order to stun schooling fish and squid.

Well.. I survived the first non-cetacean of this commission! Yesterday I painted one of my favourite sharks (lucky they’re part of the species list): the common thresher shark. Threshers have an incredible tail, with the upper lobe as long as the whole rest of their body. They use it as a whip to knock fish out cold before eating them. They also have quite incredible colours: purplish on top and azure blue on the sides, divided by a copper line. But once dead, they quickly lose all colour and turn grey.

Just to compensate, I went back to trusted familiars for the other daily illustrations haha; my old friends the killer whale and short-beaked common dolphin.
