Have you ever heard of the Angelshark (Squatina sqautina)?

It's a nocturnal ambush predator with great camouflage skills! Sadly it's critically endangered sadly because it was overfished - if you've eaten monkfish it's possible it was angelshark.

Happy #FlatSharkFriday to the Southern Stingray (Dasyatis americana)!

They live in the Atlantic from New England to South America, create huge pits to expose their food in the sediment, & communicate to each other with pheromones! Incredible animals!

Did you know THERE ARE SHARKS WHO ARE OLDER THAN THE UNITED STATES?!

Those are the Greenland Sharks (Somniosus microcephalus)! They can live between 300-500 yrs, thrive in waters at freezing temperatures, & despite swimming at 0.76 mph, they are apex predators. Amazing!

Happy #FlatSharkFriday! Ever wondered what the difference between Skates & Rays is?

A big one is that Skates lay eggs whereas Rays give live birth! Skates also tend to be smaller & lack the stinging barbs the Rays have.

Both incredible animals!

#TeethTuesday My all-time favorite shark teeth come from the incredible yet extinct HELICOPRION!
It has a tooth-whorl that looks like a chainsaw inside its lower jaw & is an underrated & awesome prehistoric shark more people should know about!

Did you know that Goblin Sharks were first discovered in Japan in 1898? Their name is translated from Japanese & derived from the japanese spirit creature, the tengu, also with a long nose & face. See the resemblance? Super interesting cross-cultural history! #sharkscience

Happy #FlatSharkFriday everyone! S/o to @elclimo for the awesome elasmo comics!

#DidYouKnow Nurse sharks are pregnant for 6 months & give birth to 21-29 pups, each ~30cm with little spots! PC: @BiminiSharkGirl #bestshark

@mcmsharksxx Fave cartoon shark is definitely any sharks that show up in the Far Side comics! Doesn't happen often but I always enjoy them.
