Paddlefish, goblin sharks and hammerhead sharks have rostrums packed with electroreceptors which signal the presence of prey by detecting weak electrical fields. Sawsharks and the critically endangered sawfish have rostrums (saws) which are both electro-sensitive and used for slashing. [9] The rostrums extend ventrally in front of the fish.
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 ...
The most distinctive characteristic of the goblin sharks is the long, trowel-shaped, beak-like snout, much longer than those of other sharks. Its long snout is covered with ampullae of Lorenzini that enable it to sense minute electric fields produced by nearby prey, which it can snatch up by rapidly extending its jaws. [ 5 ]
Mitsukurina is a genus of mackerel shark in the family Mitsukurinidae. It contains one extant species, the goblin shark (M. owstoni) and more extinct species. The genus was described by American ichthyologist David Starr Jordan in 1898 and named in honour of Kakichi Mitsukuri. [1]
The shark caught near Su’ao was the largest goblin shark ever caught in Taiwan, the museum said. The massive female shark weighed about 1,763 pounds and reached about 15.4 feet in length, Taiwan ...
Lamniformes: They are commonly known as the mackerel sharks. They include the goblin shark, basking shark, megamouth shark, the thresher sharks, shortfin and longfin mako sharks, and great white shark. They are distinguished by their large jaws and ovoviviparous reproduction. The Lamniformes also include the extinct megalodon, Otodus megalodon.
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.
Pores are concentrated in the skin around the snout and mouth of sharks and rays, as well as the anterior nasal flap, barbel, circumnarial fold and lower labial furrow. [10] Canal size typically corresponds to the body size of the animal but the number of ampullae remains the same. The canals of the ampullae of Lorenzini can be pored or non-pored.
