CRITTER: Meet ulua kihikihi, the threadfin jack

The body of the fish may only be 4 inches long, but their dorsal and pectoral fins look like long threads and are up to foot long.

Many of our Hawaiian salt water fish look very different when they are babies as opposed to being adults. The threadfin jack is so unusual looking as a baby that when divers see one, they usually have no idea what they are looking at!
