Dwarf sawtail catshark

The dwarf sawtail catshark (Galeus schultzi) is a species of shark belonging to the family Pentanchidae, the deepwater catsharks. This shark is found exclusively in the deep waters off Luzon in the Philippines. Unlike other members of its genus, this slender, diminutive shark has a short, rounded snout and very short furrows at the corners of its jaws. It has indistinct darker saddles beneath each dorsal fin and two dark bands on the caudal fin, as well as a prominent crest of enlarged dermal denticles along the upper caudal fin margin.
