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

the chilean angelshark is a rare species of angel shark thought to be extinct but has been recently redescribed. they can grow to be at least 1 metre(~3.3 ft) long and may grow larger. chilean angelsharks inhabit the muddy and sandy bottoms  in the southeastern pacific along the western coast of south america. they feed on a variety of bony fish, smaller elasmobranchs, molluscs, and crustaceans. the tips of their pectoral fins and part of their head are covered with enlarged, hook-like dermal denticles. they are considered critically endangered.

Are there any cool sharks that have sadly gone extinct? Or are in danger of going extinct?

So I've actually gone and signed up for an account on the IUCN website to look into this specifically without spending ten million years trying to find the answer. A short summary of those at risk of extinction and those already extinct below :)

According to the IUCN’s Red List (which basically gives you a run down on how close or far an animal is to extinction), searching “sharks” and narrowing down the search to CR (critically endangered), EN (endangered), and VU (vulnerable), I got 420 hits. Of those, it will include animals that have “shark” in their name; which may include non-shark fish. But I can at least narrow it down a bit further using taxonomy as a means to filter out non-shark animals. This means, for taxonomy, we look for “Chondrichthyes” as a class of animals; aka sharks and rays.

The result then narrows down to 416. These are sharks. And now I can sort the order of results from VU right the way down to CR (lower to high on the concern scale). Since we want to know the most at risk first, I can reverse this sorting so it’s most to least in danger.

There’s been no recently extinct sharks, according to the IUCN’s list, but that’s not to say shark species aren’t at great risk of extinction, or aren’t critically endangered because of a range of reasons. 

So, at the top of the list we have:

Scalloped Hammerhead

Angelshark

Oceanic Whitetip Shark

Hidden Angelshark

Argentine Angelshark

Chilean Angelshark

Humpback Smoothhound

Indian Swellshark

Daggernose Shark

Ganges Shark

Dwarf Gulper Shark

Reticulated Swellshark

Striped Smoothhound

Scoophead Shark

Sarawak Pygmy Swell Shark

Pondicherry Shark

Pacific Smalltail Shark

Borneo Shark

Shorttail Nurse Shark

Lost Shark

Smoothback Angelshark

I’ve excluded rays from this list since they’re a different sub-branch of the Chonrichthyes class to sharks. That gives us 21 sharks classed as critically endangered (aka at risk of extinction) so far on the list. This is only from the first page, by the way. 

Out of the list, one shark is potentially thought to be extinct which is the Lost Shark (good name). Only 3 specimens of the species have been found in Borneo, Thailand, and Vietnam; all are over 80 years old. They were mistaken for a species of Smalltail Shark at first, but now they’re considered to be their own species. As a result, IUCN’s Red List classifies the Lost Shark as CR or possibly extinct.

This made me sad. I need to go cuddle Greg the Mako Shark who lives on my bed to feel better now.

Species Profile No. 39: The Chilean Angelshark (Squatina armata) Today we’re featuring another incredibly mysterious shark, the Chilean Angelshark. Listed as Data Deficient, the IUCN page of this species states that “nothing is known of its biology.” These sharks don’t seem to be caught very often, but the only fisheries information about them comes from Peru, and nothing is known of their value to fisheries in any other country. While it’s a bit disappointing to make a post with so little information, we want to give you all a chance to learn a little bit about every angel shark species! Learning about how many shark species are poorly understood is also important, as it highlights the pressing need for more shark research. Remember that the best way to support species like the Chilean Angelshark is to donate directly to research groups/funding bodies, such as the Shark Conservation Fund. To help support angel sharks, make sure to support @angelsharkproject, the Angel Shark Conservation Network, Shark Advocates International, and the Shark Conservation Fund. ••• Big thanks to our Patron, Clay Herber! ••••••••••••••••••••••••• #angelsharkprofiles #shark #sharks #angelshark #disparateangelshark #mexicanangelshark #squatina #diversesharks #sharkeducation #savesharks #savethesharks #helpsavesharks #bycatch #overfishing #stopoverfishing #replacefearwithfacts #stopsharkfinning https://www.instagram.com/p/B1WeTk2BW48/?igshid=gvp78lxzq4q7
