Honeycomb cowfish

This fish, a type of boxfish, is named for the honeycomb pattern across its body, and the sharp spines above the eyes that resemble cattle horns. They vary widely in color, ranging from blue hues to green and yellow. And they are able to rapidly darken or pale.

These fish were about 12 inches long, and the photos were taken at depths of 30 to 40 feet.
