Black Trevally


The BLACK TREVALLY (called ulua la'uli) has strengthened scales that reinforce its tail.  Also called the Black Jack, this fish is easy to identify because of these scales that make a dark lined pattern leading to the tail.  They're typically almost black to dark gray, and they have a dark spot on the upper gill cover.  They're found alone or in pairs, but rarely ever in groups and can be seen near drop-offs adjacent to deep water.  They can grow to be 3 feet long.
