halfmoon

(Medialuna californiensis), edible Pacific fish of the family Kyphosidae (order Perciformes). Some authorities place it in the subfamily Scorpidinae, as distinct from the other Kyphosidae, which are known as sea chubs. Halfmoons are bluish gray in colour, with dark gray fins. They normally reach a length of about 30 centimetres (1 foot). They inhabit Pacific coastal areas from Oregon to the Gulf of California and are caught in large numbers by commercial fishermen.
