This honeycomb cowfish's body markings help it blend into the reef background at Front Porch, near Turneffe atoll. Since it's body shape doesn't allow it to be too swift in the water, that camouglage is important.

And, although I failed to make the picture where you can clearly see the front of this unusual fish, it is named for the two sharp and hard spines above each eye. This guy is in the boxfish group and distiguished from its cousins, the trunkfishes, by those horns.
