Thats one shit shark.
Having said that I find it totally amazing that these creatures haven't changed hardly in millions of years, making them the top of their respective food chain.
Good post, it looks like a cross between a moray and a beaten up shark.

awesome! i love shit like this!
cant wait till we have footage of bigfoot, nessie, or a yeti. obviously these creatures can survive for millions of years without human intervention. and if humans haven't been hunting them, then why cant they still exist today? i dunno, this type of stuff gets me exited.

Robobond, they've had instances where the cookie cutter shark would chew holes through the metal hulls of submarines or boats or something submerable. I read it somewhere a couple years ago...

Very interesting!!! That was one gnarly looking shark. I have always been intriqued by underwater life. And I truely believe in the Loch Ness--its plausible that a bottom feeder could live deep in the waters and never be discovered. And very little of the ocean population has been identified according to scientists. So anyways awesome info there... always good to hear about new creatures (to us anyway).
why in the fuck would they take it away when they already know they can only survive is special conditions...thats fucked up. they could have adleast just put a tracking device in it and observed it whenever. and find out more about where they live.
why do humans always have to act asif something is theirs just because they found it?????????

Honestley though, if I was swimming and saw that Frill Shark swimming at me, it would have to attack me through yellow water, because I would piss my pants....
Endo, what the hell is THAT?
Lampreys live mostly in coastal and fresh waters, although at least one species, Geotria australis, probably travels significant distances in the open ocean, as is evidenced by the lack of reproductive isolation between Australian and New Zealand populations, and the capture of a specimen in the Southern Ocean between Australia and Antarctica. They are found in most temperate regions except Africa. Their larvae have a low tolerance for high water temperatures, which is probably the reason that they are not found in the tropics. Outwardly resembling eels in that they have no scales, an adult lamprey can range anywhere from 13 to 100 centimetres (5 to 40 inches) long. Lampreys have one or two dorsal fins, large eyes, one nostril on the top of their head, and seven gills on each side. The unique morphological characteristics of lampreys, such as their cartilaginous skeleton, means that they are the sister taxon (see cladistics) of all living jawed vertebrates (gnathostomes) and are not classified within the Vertebrata itself. The hagfish, which superficially resembles the lamprey, is the sister taxon of the lampreys and gnathostomes (a clade termed the Craniata).
Lampreys begin life as burrowing freshwater larvae (ammocoetes). At this stage, they are toothless, have rudimentary eyes, and feed on microorganisms. This larval stage can last five to seven years and hence was originally thought to be an independent organism. After these five to seven years, they transform into adults in a metamorphosis which is at least as radical as that seen in amphibians, and which involves a radical rearrangement of internal organs, development of eyes and transformation from a mud-dwelling filter feeder into an efficient swimming predator, which typically moves into the sea to begin a predatory/parasitic life, attaching to a fish by their mouths, secreting an anticoagulant to the host, and feeding on the blood and tissues of the host. In most species this phase lasts about 18 months. Whether lampreys are predators or parasites is a blurred question.
Not all lampreys can be found in the sea. Some lampreys are landlocked and remain in fresh water, and some of these stop feeding altogether as soon as they have left the larval stage. The landlocked species are usually rather small.
To reproduce, lampreys return to fresh water (if they left it), build a nest, then spawn, that is, lay their eggs or excrete their semen, and then invariably die. In Geotria australis, the time between ceasing to feed at sea and spawning can be up to 18 months long.
Recent studies reported in Nature suggest that lampreys have evolved a unique type of immune system with parts that are unrelated to the antibodies found in mammals. They also have a very high tolerance to iron overload, and have evolved biochemical defenses to detoxify this metal.
