Brown Shyshark <3

This shark is harmless to humans and is even considered a minor pest species. Because of this they are usually discarded or killed when hooked.  Shysharks will curl up into balls and cover their faces with the ends of their tails when frightened, which im pretty sure is where they got their name!! 

This shark is sedentary bottom dweller feeder! They feed on boney fishes and also lobsters. They are a sister species of the Dark Shyshark!! 

i think i love them very much and i hope these sharks have a very good day!!

Top ten shark facts? 🦈

I mean I don't rly rank shark facts, so heres just ten random ones:

1. Lemon sharks have a buddy system, where they will stick to another shark for higher chances of survival. They swim so closely to each other sometimes, that it looks as if they're holding hands...or rather fins.

2. Great white sharks can change the color of their upper body half to better match the surrounding water aka they're capable of camouflaging themselves!

3. Hammerheads are amazing at finding prey, due to the hammer having a bigger amount of ampullae of lorenzini (tiny organs that can detect electromagnetic fields). They swerve their hammer left and right to scan the area and can detect stuff like stingrays even when they are buried in the sand.

4. The waters around Australia have the biggest variety in shark species! If you want to encounter loads of different ones, thats the place to go! Theres said to be over 150 species there!

5. Sharks have the ability to remember and recognize humans. They respond positively cuddly to divers that have helped them before and Cristina Zenato (the women thats known for removing hooks from sharks) has described experiences where the shark will lie in her lap and let her remove the hook peacefully, because it knows she will help. This speaks a lot for their intelligence.

6. There are shark species that are capable of biofluorescence (absorbing & the reemitting light) and bioluminescense (producing the light themselves). An example for the first one would be shy swell sharks and an example for the latter are kitefin sharks.

7. Tiger sharks are known as the garbage cans of the ocean, because they are capable of eating absolutely everything. Not only do they have super strong jaws & teeth, but their stomachs are actually highly acidic and have barely any problems breaking down the weirdest things.

8. The dark shyshark gets the second half of its name due to its reaction when threatend. It actually curls up and puts its tail over its eyes!

9. The cookiecutter shark actually cuts cookie shaped holes into its prey and usually does that while the prey is still moving, kinda like a snack to go. They also are known for biting into submarines.

10. The hierarchy between different shark species in an area is not always just determined by size or strength. The amount of time the shark has spend there and how familiar it is with the environment, plays a role as well! Some researchers observed a big shark making place for the smaller ones, because it was still new to the area.

(All facts stem from documentaries, scientific papers or the pages of professional divers. I do however not guarantee that they are definitely correct, or haven't been disproven since)

earth fact time. meet the shyshark, the largest species of catshark. when they get scared, they curl up with their tails over their eyes, which is why they're called shysharks!

If Jackie were an Anphian she'd be based off a black tipped reef shark and a dark shyshark. Yes, these are smaller reef species, yes she'd be a smaller reef kinda Anphian, but that just means she grows all kinds of weird sea life to stop dead zones from forming.

Juvenile dark shysharks have slender bodies, while adults are more stocky.

You're super interesting! Here watch: know any cool shark facts?

I definitely am not interesting, but I get to talk about sharks so its okay. (I guess I’ll just give my random favorite…. this might get long)

ooookay to start um…

-Most sharks, like great whites and makos, will drown if they stop moving because the don’t have the muscles necessary to move water through their mouths and over their gills. We didn't really know if sharks slept because they have to keep moving at all times, but last year when I watched shark week, on one of the shows scientists seemed to catch a shark “sleeping” using a robotic submarine with cameras all over it. If I remember correctly the shark (a great white) went into this sort of catatonic state at some point in the night and slowly swam against the current with her mouth open, allowing for water to flow over her gills, and for her to save energy. (Unrelated to the sleeping thing, this is why shark nets are so dangerous for them. They get caught and suffocate when they’re unable to move/breathe)

(I think this is the video from discovery)

-The great white is on average 15 feet in length, the dunkleosteus (not a shark, but a placoderm fish from the Late Devonian period (I just think they’re cool)) on average was 35 feet long, and the megalodon 80 feet long.

-The dwarf lanternshark is considered the smallest shark at about 7 inches in length. The second smallest is the pygmy shark, at 8 to 10 inches

-Sharks are cartilaginous. Teeth are the most common shark fossils one can find because most of the cartilage skeleton dissolves in salt water, but, while it is uncommon to find full body fossils, there are fossils of vertebrae, rostral nodes (kind of like its nose), and dermal denticles, which are the tiny scales that make up a shark’s skin. Basically parts of the shark with the densest cartilage.

(Because I’m lame, here’s the first link that pops up when you google “shark fossils”)

-I think it’s like 50 different species of sharks use bioluminescence. These sharks come from the Etmopteridae and Dalatiidae families.

(Article about “glow in the dark” sharks)

(A synthesis talking about the two bioluminescent sharks (It’s a bit hard to read but still cool!!))

-Sharks are like 400 million years old and have survived (all?????) five major extinctions.

-To answer something that I’m often asked: sharks Do have tongues. Its a piece of cartilage at the floor of its mouth that lacks taste buds and is called the basihyal. It doesn’t really do anything, but the cookiecutter shark uses it along with its teeth to help rip chunks of flesh out of it’s prey.

-The elegestolepis shark is considered the first shark and lived during the Silurian and Devonian periods. We really don’t know what it looked like and can only identify it from its scales.

-The Carboniferous period is sometimes called the Golden Age of Sharks. By the end of this period there were 45 families of sharks.

-The ginsu shark (cretoxyrhina mantelli), a prehistoric shark, would have been about the size of a bus.

-The puffadder shyshark is a catshark (the fact that we have “cat sharks” and “dogfish sharks” just really gets to me. idk i just love it so much)

-Bat ray fossils dating back to a million years have been found.

-Some rays, like bat and manta rays “flap,” and others move their body by undulating like a wave.

(Blue spotted stingray; waving motion)

(Bat ray; flapping motion)

-Stingrays are born fully formed and able to be self-sufficient, but will stay with their mothers until about age 3 (this is different from sharks, who  don’t care for their pups after their birth)

Other facts:

I really like sharks

I tag all shark posts as #sharkive

There is also a tab on my blog leading to that tag

You can send me posts about sharks or rays at any time

And I will love you for it

And probably definitely cry

This is another ask I was sent asking about sharks

Yeah so. I know it was supposed to be about sharks but I love rays so I incorporated the shark cousins at the end. Have fun with the shark facts here’s my favorite gifs

[snoozlord]

and here’s very cute pictures of a dark shyshark

[sharkfactoftheday]

Terms like “shyshark” and “donut” that emerged in response to shysharks’ defensive behavior can be applied to multiple species. To keep this from confounding research, academics use “Happy Eddie” as an easy-to-remember name for puffadder shysharks, based on the scientific name Haploblepharus edwardsii. "Plain Happy,” “pretty Happy,” and “Happy chappie” refer to brown, dark, and natal shysharks respectively.

[sharkfactoftheday]

Reproduction has been investigated in the puffadder and dark shysharks. Neither species appears to have a distinct breeding season, and their eggs take around 3.5 weeks to hatch.

[sharkfactoftheday]

Based on mitochondrial DNA, the brown shyshark and dark shyshark are sister species- they are more closely related to one another than any other known species.
