Description
The largetooth cookiecutter shark is a small deep-sea shark (Dalatiidae) from tropical and temperate oceans worldwide. The species grows to about 42 cm and has a cigar-shaped, brown body with light-producing organs and a ring of extremely large lower teeth. It attaches to much larger animals such as whales, tunas and sharks with its sucking lips and twists a round plug of flesh from their skin. By day it stays in deep water and rises at night. Attacks on humans are rare but possible; the bite leaves a round, deep wound.
