Got any cool info on cow sharks?

YES

There are five species of cowshark: Broadnose sevengill, Bluntnose sixgill, Sharpnose sevengill, Bigeyed sixgill, and the Atlantic sixgill.

My favorite fact about these adorable little sharks is that they have more gills than most sharks do (which is why its mentioned in their name). Most sharks have five gill slits! They also don't have the notably large dorsal fin synonymous with sharks.

These sharks have even been observed to hunt in packs for larger prey like seals and other sharks! They're commonly found in shallow, warm waters.

HELLO. as some of you may know i went to a very Big aquarium on monday and i said i would post pictures. this is it. BUADBKASBDKJ

this is a broadnose sevengill shark. when i came to the aquarium i was most excited to see these little guys (well, not technically little but theyre just Guys) as the name implies, they have seven gill slits instead of the regular five. you may also notice that they look a bit prehistoric. thats because they kind of are. sevengills are a type of cowshark which is in the same family as frilled sharks and they are some of the oldest sharks that are still swimming around down there. i personally love cowsharks i find them to be very cute and i was literally crying when i saw them in the tank

this is a spiny dogfish. this is the most Normal picture i got of this guy the entire time. he was literally following me and i know it was the same guy because his nose was kind of bloody. which poor little guy but also it was very funny that he kept coming up to me.

here is another picture of the same spiny dogfish. no joke he was following me. if i can upload the video i took i will.

ANYWAY. i dont actually know that much about spiny dogfish but i should get on that tbh. i will forever stand by my statement that dogfish sharks are the silliest guys in the whole ocean and i LOVE silly sharks

this is a scalloped hammerhead. i dont actually know very much about this particular species either but i do know that they, as a whole, have a symbiotic relationship with barberfish. the hammerheads swim near the barberfish and when they jerk their tails, the barberfish know to go clean their teeth. its like a little shark dentist. in this particular picture, this was the only hammerhead in the tank, which has 1.2 million gallons of water in it and nothing on the bottom to imitate the open ocean for pelagic fish and turtles. (there were two turtles they were very cute but i am not a turtle guy so i will not be talking about them)

this is a leopard shark. they had A Lot of leopard sharks everywhere. there were a lot in this tank that i took this picture in and then there were a few in the sevengills tank and there were like two or three in a shallower pool with some bat stingrays (which are adorable and i will be learning more about them because they are so fucking cute)

extra pictures under the cut :D

Close Shark Encounter - Very Close! A Bluntnose Sixgill Shark To Be Exact. This is a two part video. • This is a #repost from @ocean_syrup via @PhotoAroundApp The "prehistoric" Six Gill Shark, spotted at over 500m deep. The @oceanx crew used a submersible to tag it, opening up new possibilities for tagging deep sea creatures without having to bring them to the surface(which can be harmful).

Bluntnose Sixgill Shark Fact Sheet!

It’s about time I made one of these, considering all the time I’ve put into researching them. I still have. . . 30 more papers to read out of 64, so I will update this post as I learn more.

> The taxonomic name of the bluntnose sixgill shark is Hexanchus griseus. It is under the family Hexanchidae, which are known as the “cow sharks.”

> Sixgills are globally distributed on continental slopes, shelves, and sea mounts, except for the Arctic and Southern oceans.

> Sixgills are ovoviviparous, which means their young develop in egg sacks within the mother’s uterus. They give birth to up to 108 pups and are polyandrous, which means one litter was multiple contributing fathers.

> Sixgill pups start out with a total length of 68-73cm, and can grow up to 5m!

> Sixgills occupy deep waters during the day and shallower waters at night, migrating up and down the sea floor slopes at dusk and dawn.

> A group of sixgills is called a shoal. The largest recorded gathering of sixgills was a shoal of 21 sharks.

> Sixgills share a genus with two other species, the Atlantic sixgill shark (Hexanchus vitulus) and the bigeye sixgill shark (Hexanchus nakamurai)

> Hexanchid teeth have been found as far back as the Eocene epoch, about 33.5 to 56 million years ago.

> Sixgills growing up in Puget Sound have friends! They can often be found in pairs with same-sex conspecifics.

> Sixgills are generalist scavengers that spend most of their time above the sea floor (epibenthic).

> These sharks occupy depths up to 2500m.

> Sixgills give birth about once every two years.

> Sixgills are docile sharks, and have never harmed a human.

> Males have “scrolls” which sheath the claspers, making sexing at a glance more difficult than with other sharks species.

> We have yet to develop a method of determining the age of these sharks due to poor skeletal calcification. We don’t know how old they are or how long they live.

> Sixgills have comb-like teeth on the lower-jaw which allow them to saw and shear off chunks of flesh from bodies.

> A sixgill shark was responsible for biting a submarine fiber optic cable on a certain clip recorded by a commercial ROV in 2003!

> A sixgill shark once gave a ride to a crab on her fin! Her name is Crusty.

60 second look at False Bay. Heading back to one of South Africa's three white shark dive destinations we consider some of the "x-factos" of False Bay. Yes, it's still the best place to see high flying white sharks hunting seals, but did you know you can dive with other species of sharks in the relative area? Conveniently only an hour south of Cape Town, Simon's Town is the embarkation point to see white sharks (Seal Island), blue sharks (past Cape Point in the open sea), and cow sharks (in the kelp forests of pyramid rock. The blue shark dive is one of the best I've ever been on. These animals have no problem coming in close to have a look at you so your chances of close encounters and good footage are high. You might be lucky enough to see a mako shark too, but both makos and blue shark numbers are dwindling due to overfishing, particularly from long lining. If you've never dove in a kelp forest that alone is a reason to do the cow shark dive. This prehistoric species of shark glides slowly and calmly through giants stalks the reach toward the surface above. An interesting bit of trivia; cow shark numbers have improved in recent history partially due to the white shark dive industry no longer using their oily livers as attractants!

Truth! Sea slugs are always excellent, and sharks outside the big free-swimming hunters need more love.

Also TIL just looking something up related to this post: whale sharks are a kind of carpet shark! They’re in the same order, the Orectolobiformes, as nurse sharks, zebra sharks like the bottom-left up there (you can see the similarities looking down at them like this!) and a bunch of other bottom-feeding sharks like wobbegongs - like this tasseled wobbegong here:

Quick shark lesson: the big free-swimming hunters everybody thinks of when they hear "shark" are mostly either requiem sharks like the tiger sharks and reef sharks, or mackerel sharks. Requiem sharks are a family inside the ground sharks, the Carcharhiniformes - which also includes the houndsharks like leopard sharks, a bunch of smaller sharks like the catsharks, and hammerheads!

Mackerel sharks are their own order, the Lamniformes, like the ground sharks or the carpet sharks. Great whites are mackerel sharks, so are threshers and makos, so was Megalodon. Tumblr's favorite weirdo shark, the goblin shark, is also a mackerel shark! These three orders basically form one of the big branches of the shark group, along with the Heterodontiformes - bullhead sharks like the horn shark. This whole branch is called the Galeomorphii.

The other big branch is the Squalomorphii. It's made of the orders Pristiophoriformes (the sawsharks - not to be confused with sawfish, which are technically rays that look more like sharks), the Squaliformes (dogfish sharks), the Squatiniformes (angelsharks, who are basically sharks that look more like rays), and the Hexanchiformes (frilled sharks, which are long snaky deep-sea critters, and cowsharks, which are slightly less snaky)

The Galeomorphii and Squalomorphii together make up the Selachimorphia, which is basically every shark. The Batoidea, the rays, come from the same common ancestor. Together they make up the Elasmobranchii, which are most of the Chondrichthyes, the cartilaginous fish. (The others are less closely related - the Holocephali are a bunch of deep-sea fish called chimaeras, with long skinny tails, various funny-looking faces on account of actually having lips, and basically no stomaches - their gut is basically all intestine.)

Some of the most underrated marine animals and you can’t change my mind

Who wants to keep learning about sharks?!! We're still going through our lineup of shark friends - and there's only 3 left! . This is Graze, the Cow Shark. Graze is a social butterfly and is naturally very outgoing, considering she spends most of her time in the deep oceans. . Cow sharks are a family of sharks characterized by an additional pair or pairs of gill slits and there are about 37 species of sharks in this family, including the Broadnose Sevengill Shark and the Bluntnose Sixgill Shark. . Cow sharks are considered the most primitive of all the sharks, as their skeletons resemble those of ancient extinct forms, with few modern adaptations. Their most distinctive feature, however, is the presence of a sixth or seventh gill slit (depending on species), in contrast to the five found in all other sharks. They are most closely related to Frilled Sharks. . ∘₊✧ https://etsy.me/2RIfxUd ✧₊∘⠀ . #sharks #cowshark #sixgillshark #sevengillshark #fishfacts #ilovesharks #sharkfacts #savesharks #sharkcartoon #savethesharks #letslearnaboutsharks #bytesizetreasure #sharkfriends http://bit.ly/2Gyt2nr
