Box and Cowfish; Ostraciidae

These characterful fish have a solid, squarish, bony carapace which effectively limits their movement but at least makes the adults uneatable to most predators. They are great subjects for underwater photography when we’re scuba diving.

Boxfish; Ostracion cubicus

The juvenile has the eye-catching bright yellow colouration - the adult a more drab hexagonal patterning.

Longhorn Cowfish; Lactoria cornuta

Named after its long horns, but what they are used for is unclear...
