Also, the tropical fish, thornback cowfish (Lactoria fornasini), has various vernacular names including thorny-back cowfish, thornback boxfish, spinybacked cowfish, blue-spotted cowfish, thornback cow, backspine cowfish, and many more. This tropical fish from the Indo-Pacific has an omnivorous diet, primarily feeding on invertebrates, krill, shrimps, clam, mussels, and marine algae.
