A group of sharks is called a shiver (although, as fish, they are often simply called a school).

shout out to goblin sharks and their weird ass jaws! Goblin sharks have a special trait called a “slingshot jaw” where they snap their jaws forward to capture prey. their mouths can extend to up to 110 degrees wide, and shoot out at about 3.1 meters per second!

here’s a diagram of how it works:

DYK…

grey reef sharks appear grey from a distance, but actually have a bronze tint to their skin.

grey reef sharks do not pose a threat to humans, but have been inquisitive around divers. if there is food in the water, this shark will become very active and even aggressive. the expected lifespan is estimated to be at least 25 years.

grey reef sharks are less than 1.9 m (6.2 ft) long. the maximum reported length is 2.6 m (8.5 ft) and the maximum reported weight is 33.7 kg (74 lb).

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.

bts as my favourite sharks !!! (and why)

.　 . • ☆ . ° .• °:. *₊ ° . ☆.

(a list no one asked for but i will deliver) 🦈🫧

☆ namjoon: bull shark

one cool thing about bull sharks is that they can swim in both salt water and fresh water, super adaptable, super cool and hence why they’re namjoon. and in my humble little opinion, they’re just cooler versions of the great white 🧍🏻‍♀️ plus they’re like the big boy shark top of the shark food chain, perfect place for our favourite guy namjoon

☆ hobi: lemon sharks

i love lemon sharks because they have favourite humans, and love head pats, and form emotional connections with divers, and get jealous when their fav human being shows and attention to another lemon shark. 10/10 sociable shark, perfect for hobi

☆ jungkook: tiger shark

tiger sharks are just built different. and have probably had anything you can think of in their stomachs, they eat anything. they’re also known for having huge litters and after ‘seven’ and ‘3d’ 🤨 plus tiger sharks make it into my top 3 favourite sharks so maybe i’m a little biased

☆ yoongi: whale shark

whale sharks are gentle giants, and have been one of my favourite sharks since forever. and i think people think they’re scary because they’re huge, like school bus size. but they’re just cuties :( who eat lil shrimp and algae and have lil teeth and are so pretty. also random whale shark fact they can process more than 6000 litres of water every hour 🫡

☆ jimin: thesher shark

honestly just silly little guys 10/10 my favourite shark. they look like cuties but thresher sharks can stun their prey with their super cool tails, which i think if we’re looking at jimin and the sassy man agenda… don’t let cute looks fool you. also!!!! thresher sharks can jump out the water and do cool flips, comparable to jimin’s super cool contemporary dancing ☝️

☆ jin: hammerhead shark

a distinctive shark, and a distinctive face. hammerhead’s haven’t actually been around for as long as other species of shark, only existing for around 20-25 million years (where other sharks have been around since the dinosaurs), which may seem contradictory to jin’s age, however, this mf doesn’t age and has looked as young as he did the day he debuted

☆ tae: blacktip reef shark

black tip reef sharks are a little shy and skittish, and tae is often a little bashful, especially on live (in a very very taehyung way), so i feel they fit one another. however! that doesn’t mean they’re not social, which with bts and the wooga squad and everyone else tae meets, 10/10 black tip reef shark kinda guy

Whale sharks have unique spot patterns that function like fingerprints in the way they can be used to recognize individuals

Fun fact most sharks can live up to 20-30 years but some can go up to longer!

We've even seen them in fossil records long before trees, isn't that interesting?

Exciting news for the cute shark lovers of the world! We finally have a recorded sighting of a baby great white shark, likely only a few hours old.

The question of where great white sharks give birth still remains a mystery to this day but this footage may suggest the coasts of California, where the footage was taken, are a site where these sharks give birth.

🦈 Daily Shark Fact: 🦈

The Taiwan Spurdog was accidentally discovered in a Taiwanese fish market by two scientists. This endangered shark is endemic to China, Taiwan, and South Korea. There is not much known about its behavior as it lives in depths up to 2600ft near the continental shelf. They are assumed to be very shy, as there is no record of divers having ever seen the Spurdog during explorations.

Because I'm going to school for bio anyway I've decided I'm going to make a series where I just post about random animals I find cool and a couple facts about them. I don't know how frequent this will be, but first creature on the list is-

Chain Catshark

Also known as the chain dogfish, chain catsharks are a nocturnal catshark that get up to 59 cm in length. They're found most commonly in the Northwest Atlantic and Western Central Atlantic. They're generally shy, and harmless to humans, their diet consisting of squid, bony fish, crustaceans, and bristle worms.

But the most interesting thing about them is that they're biofluorescent, and one of only four elasmobranch species with this ability!

Look at her! Isn't she gorgeous? I don't have much more to add rn but feel free to admire her beauty until next time I have an animal post

DYK…

tiger sharks are non-selective feeders and a voracious predator. they has been known to consume a wide variety of marine prey and even some terrestrial animals. common prey include crabs, shellfish, lobsters, squid, bony fish, small sharks, skates, rays, porpoises, turtles, marine birds and mammals.

tiger sharks are apex predators meaning they don't have many natural predators. in fact one of the only known predators to this species are humans and killer whales. a killer whale is much larger in size and weight, which allows it to overpower the shark.

tiger sharks are named for the dark, vertical stripes found mainly on juveniles. as these sharks mature, the lines begin to fade and almost disappear.
