Smooth trunkfish

Earlier, I posted photos of the spotted trunkfish.  The smooth trunkfish is a close relative.  They are in the same genus.  This species reaches 10 to 12 inches in length, but these photos were taken of juveniles that weren't bigger than 3 inches.  The smooth trunkfish is a member of the boxfish family, with a triangular, boxy skeleton.  Today, I took a photo of the broad, flat bottom side of one.

All the photos were taken at depths of 20 to 25 feet.

This fish is the smallest, about the size of a thumbnail.  It is facing downward.

Bottoms up!
