Scuba

Ostraciidae
Known variously as boxfishes, cowfishes, trunkfishes and cofferfishes, they are closely related to pufferfishes and filefishes.  These two were photographed in Padang Bai Harbor, Bali, Indonesia diving with Pak Wayan.

Thornback Cowfish, Lactoria fornasini.
Weak swimmers because of their box-like carapace but this also makes them difficult for other fish to eat.  It that alone does not deter, boxfish secrete cationic surfactants as a chemical defense shield when they are under stress.

Difficult to shoot from the front, they usually turn and slowly flee looking for crevices to hide.
