The caudal fin is low and somewhat triangular, without a lower lobe. The nostrils are vertical slits, separated into incurrent and excurrent openings by a leading flap of skin. I think I fixed it well enough. The lower jaw seems to undergo more complex movements and is key in capturing the prey. His contemporaries Theodore Gill and Edward Drinker Cope suggested it was instead related to the hybodonts , which were the dominant sharks during the Mesozoic era. It has been hypothesized that frilled sharks, surviving the mass extinction of the K-T boundary event, were able to make use of vacated niches in shallow water and on continental shelves, the latter opening up a move to the deep-water habitats they now inhabit. Therefore, it is not believed to be threatened by human activity. Does it have any implications as far as function goes? In the eastern Atlantic, it occurs off northern Norway , northern Scotland , and western Ireland , from France to Morocco including Madeira , and off Mauritania. Because of its very low reproductive rate and the continuing expansion of commercial fisheries into its habitat, the International Union for Conservation of Nature IUCN has previously listed it as Near Threatened , although the species was downlisted to Least Concern in The picture is so pretty, but pictures in Wikipedia really aren't my thing: Report it to Wikizine The rear teeth near the corners of the jaw are small and have a flattened shape for crushing. With a mouthful of needle-sharp teeth. The eyes are large and rounded. It was brought to Awashima Marine Park in Shizuoka , where it died after a few hours. A single eastern Pacific specimen is known, collected off southern California. However, his manuscript describing the species was lost, so the first description of the frilled shark was authored by American zoologist Samuel Garman , working from a 1. The fins' margins are translucent gray or blue, and the eyes are black with bluish streaks in the iris. The specimen had been acquired by shipmaster and naturalist Alan Owston , who had given it to Professor Kakichi Mitsukuri at the University of Tokyo , who in turn had brought it to Jordan. Its jaws, buccal cavity , and abdomen are all highly distensible, suggesting that this shark is specialized for capturing and swallowing whole large prey, with its rows of needle-like, recurved teeth preventing escape. Even with the picture I cannot tell what it means, but it must be an important feature. Life history[ edit ] Little is known about goblin shark reproduction because a pregnant female has yet to be found and studied. This configuration is thought to be basal in sharks and may enhance its sensitivity to the minute movements of its prey. Someone with the proper expertise should merge or redirect Shark-snake to this article, if appropriate.

Prehistoric Frilled Shark




The lower jaw has a velocity about two times greater than the upper jaw because it not only protrudes forward, but also swings upward to capture the prey, and the maximum velocity of the jaws is 3. Cope went as far as to assign this species to the fossil genus Didymodus. However, his manuscript describing the species was lost, so the first description of the frilled shark was authored by American zoologist Samuel Garman , working from a 1. The goblin shark feeds mainly on teleost fishes such as rattails and dragonfishes. One was kept at Tokai University and lived for a week, while another was kept at Tokyo Sea Life Park and lived for two days. Previous research on other Chlamydoselachus species has shown that individuals living in shallower water had larger and stronger teeth for eating hard-shelled invertebrates. Mitsukurina itself first appears in the fossil record during the Middle Eocene c. The proportional length of the snout decreases with age. It has 35—53 upper and 31—62 lower tooth rows. Unsurprisingly, there is no defined breeding season for either sex, as this shark inhabits depths at which there is little to no seasonal influence. The specimen had been acquired by shipmaster and naturalist Alan Owston , who had given it to Professor Kakichi Mitsukuri at the University of Tokyo , who in turn had brought it to Jordan. The embryonic growth rate averages 1. The head is broad and flattened with a short, rounded snout. The caudal fin is very long and roughly triangular, without a lower lobe or a ventral notch on the upper lobe. The very long jaws are positioned terminally at the end of the snout , as opposed to the underslung jaws of most sharks. Even with the picture I cannot tell what it means, but it must be an important feature. It also consumes cephalopods and crustaceans , including decapods and isopods.
