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 3.14 m/s. The goblin shark has a re-opening and re-closing pattern during the strike, a behavior that has never been seen in other sharks before and ...
Scapanorhynchus texanus, Menuha Formation (Upper Cretaceous), southern Israel. Near-complete fossil of S. lewisii, under special lighting. Scapanorhynchus (from Greek: σκάφιου scaphion, 'shovel' and Greek: ῥύγχος rhynchos 'snout') [3] is an extinct genus of goblin shark that lived during the Cretaceous period, from the Aptian to the end of the Maastrichtian.
They also possess long, protrusible jaws. [6] When the jaws are retracted, the shark resembles a sand tiger shark, Carcharias taurus, with an unusually long nose. Its nose resembles the nose of a goblin, which is how it received its name. These sharks have only been seen about 50 times since their discovery in 1897.
The snout contains sensory organs to detect the electrical signals given off by the shark's prey. [16] They also possess long, protrusible jaws. [17] When the jaws are retracted, the shark resembles a grey nurse shark with an unusually long nose. Goblin sharks include one living genus and three extinct genera. [18]
The goblin shark was pregnant with six babies, or pups, the museum said in a June 15 Facebook post. The pups were between about 3.9 and 4.2 feet long and each weighed about 8 pounds.
Helicoprion is a genus of extinct shark-like [1] eugeneodont fish. Almost all fossil specimens are of spirally arranged clusters of the individuals' teeth, called "tooth whorls", which in life were embedded in the lower jaw.
Anomotodon is an extinct genus of shark related to the extant goblin shark (Mitsukurina owstoni).The distribution of Anomotodon fossils is worldwide, in formations indicating that members of the genus lived from the Early Cretaceous epoch through the Eocene epoch, and perhaps through the Oligocene as well.

The snout bears a superficial similarity to the goblin shark (Mitsukurina owstoni), some Apristurus catsharks, and the long-nosed chimaeras, all found in the deep sea. [6] With long jaws and numerous small teeth, the daggernose shark is well-suited for capturing the small schooling fishes that comprise most of its diet.
