The goblin shark's jaws extend dramatically when feeding. The goblin shark has a distinctively long and flat snout, resembling a blade. The proportional length of the snout decreases with age. [19] The eyes are small and lack protective nictitating membranes; behind the eyes are spiracles. The large mouth is parabolic in shape. The jaws are ...
Great whites possess large, dagger-like teeth; basking shark teeth are much smaller 5–6 mm (0.20–0.24 in) and hooked; only the first three or four rows of the upper jaw and six or seven rows of the lower jaw function. In behaviour, the great white is an active predator of large animals, not a filter feeder.
Male hybodonts possessed fin claspers used in mating, like modern sharks. [10] Hybodonts had a fully heterocercal tail fin, where the upper lobe of the fin was much larger than the lower one due to the spine extending into it. [17] Like living sharks and rays, the skin of hybodonts was covered with dermal denticles. [18]
There are furrows at the corners of the mouth extending onto both jaws, with those on the lower jaw almost long enough to meet at the midline. [3] The tooth rows number 41–55 in the upper jaw and 34–45 in the lower jaw; each tooth has a slightly oblique, smooth-edged cusp in the center and 1–2 small cusplets on either side. [ 5 ]
The crocodile shark has a spindle-shaped body with a short head and a bulbous, pointed snout. The eyes are very large and lack nictitating membranes (protective third eyelids). The five pairs of gill slits are long, extending onto the dorsal surface. The sizable, arched jaws can be protruded almost to the tip of the snout and contain large ...
The shark from "Jaws" is the stuff of legends.Fifty years after the movie was filmed off the coast of Martha's Vineyard, the shark from the movie is still a part of the talk of summer.
The top jaw has jagged, cusped teeth and the bottom jaw has comb-shaped teeth. Its single dorsal fin is set far back along the spine towards the caudal fin, and is behind the pelvic fins. In this shark the upper caudal fin is much longer than the lower, and is slightly notched near the tip. Like many sharks, this sevengill is counter-shaded.
