GUYS NEW SHARK JUST DROPPED

Well, technically it's not new : it's a nurse shark. What's new, however, is that it's the first xanthic (imagine albinism but in yellow) nurse shark ever found !! Not only it's not common AT ALL to find fishes with xanthism (it's the first cartilagenous fish ever recorded with this type of genetic "anomally"), but if it's there and still existing as an adult, it means the species is chill-ish with other predators (it probably would have been eaten by then). Its eyes are white so it can also be a form of albinism, in addition to xanthism !!!!!

And most of all : ITS SO CUTE !! AND IT'S SUCH A COOL FIND !!

Please if a marine biologist or someone with more info can interact with this post to feed me some more info or correct me on wrong infos i'e given I'd love it !

(Also if you have pics of animals with xanthism, it's also very appreciated!!)

Helloo, I just found your blog and it brings me great joy. Have you done a post on epaulette shark facts yet? They are my favourite 🥺

Hemiscyllium ocellatum // Epaulette Shark

Thank you so much! Epaulette sharks are one of my favorite sharks too, it's been a while since I did a post on them, so here we go!

Probably the most interesting fact about Epaulette sharks is that they can walk on land.

That might be a bit of an exaggeration, but they can move and survive on land for up to an hour!

These sharks have evolved the ability to undulate their pectoral and pelvic fins in a way that allows them to "walk" across surfaces. Their musculature and skeletal system is different from most other sharks, allowing them to lift and move their body even without the help of buoyancy underwater. They can regulate their breathing and heart rate to survive in these low oxygen conditions.

You might be wondering why these sharks do this. When the tide lowers, there are small pockets of water that larger predators cannot access. During these periods, they have less competition when hunting and additionally don't have to worry about their own predators such as other sharks and groupers. Hunting prey also becomes easier when the prey has nowhere to go.

There are nine species of this "walking shark" and they can be found in Indonesia, Australia, and Papa New Guinea. These sharks can grow up to 107 cm (42.1 in) long and eat primarily small fish, crustaceans, and polychaete worms.
