Titanium triggerfish (Balistoides viridescens)

   A yellow head with a dark, mustache-like area above the upper lip. The spherical eyes can move independently of each other. The base of the caudal fin and the lower part of the head are white. The large upper jaw contains two rows of teeth: four pairs in the outer row, three pairs in the inner row. The lower jaw contains a single row of three pairs of teeth.
