Black or Spotted Boxfish (Ostracion meleagris): Sometimes called the Trunkfish, the Boxfish has its body fully encased in a bony carapace of fused scales. Thus it swims slowly and relies on this coat of armour to deter predators. If attacked it can also release a powerful poison. It feeds on a variety of bottom-living animals especially sponges, sea squirts and soft corals plus worms and snails. Growing to between 20 and 30 cm, Males have white-spotted black tops above blue sides with yellow spots. Females are more uniformly black with white spots. Look carefully for if you notice that the dorsal and anal fins are spotted as well then it's a Pufferfish not a Boxfish.
