Distribution and habitat
editThis shark is endemic to marine waters off Dapitan, Philippines. All three specimens have been caught in water approximately 500 metres (1,600 ft) deep.[1]
Anatomy and appearance
editIt has enlarged denticles on the caudal fin, giving it a ''sawtail'' appearance like all other sawtail catsharks. The shark's body and caudal fin are not blotched. It also grows to 50 centimetres (20 in) TL and has more vertebrae, distinguishing it from all other catsharks.[1][2]
Etymology
editThe shark is named in honor of German philanthropsist Jürgen Friedrich, the co-founder of the JAF Foundation in Switzerland, because of his commitment to marine conservation, research, and advocacy.[3]
