Smooth trunkfish

The smooth trunkfish is a member of the boxfish family.  It has a boxy skeleton that is triangular in cross section: narrow at the back, and quite broad along the belly.  This species is easy to approach.  Adults occasionally grow past 10 inches, but most are 6 to 10 inches long.

Early juveniles of this species take refuge in and around reef structures.  They resemble a brown pea with white polka dots.  This morning, I found an early-juvenile smooth trunkfish, and took quite a few photos of it.  This little fish was about 25 feet deep, and was 1/2 inch in diameter.  They are really hard to photograph, because they are always moving, and my camera has a short delay between the time I push the button and the picture is taken.  Many of the photos were rear-end shots.  These were the best.  If you look closely, you can see the snout, the eyes, and the fins.

This fish is facing the coral, the tail is wrapped to the right.
They are fun to observe over the season as they grown larger.
