Gulper shark

(Centrophorus granulosus)



The gulper shark (Centrophorus granulosus) is a long and slender dogfish usually about three feet in length generally found in deep,murky waters all around the world.It is a light grayish brown,paler ventrally,with a long snout and large greenish eyes.This deep water shark has two dorsal fins with long,grooved spines and the second dorsal fin smaller than the first.Its upper teeth are blade-like and lower have finely serrated edges.This tertiary consumer feeds on mainly fish such as bony fish,but also cephalopods such as squid and other invertebrates like crustaceans.The gulper shark is currently a vulnerable species mainly because of exploitation by humans and their abnormally long gestation period and low fecundity,preventing their population from recovering.
