Gymnosarda unicolorBonito  Geographic Range  Dogtooth tuna
(Gymnosarda unicolor) are found in the Indo West Pacific, from
Australia (the Great Barrier Reef) to East Africa and the Red
Sea, and in the waters off of the coast of Japan and the
Philippines, New Guinea, Marquesas, Tahiti, Tuamotus, Pitcairn,
and Oeno Islands. (Fishbase, 2007)   Dogtooth tuna are typically
pelagic, but are known to come inshore and are found around
coral reefs and atolls at depths from 15m (50ft) to 45m (150ft).
They prefer water temperatures between 21°C (70°F) and 26°C
(80°F). They are migratory; their movements are linked to water
temperatures and the fish they feed upon. (Fishbase, 2007)
