Checkered Pufferfish

Found singly, or in schools, over rubble, sand, and seagrass beds, in protected, shallow, coastal bays, tidal creeks, and coastal reefs, hiding by burying in the sand, when alarmed.

The bodies of Pufferfish are covered in a toxic mucus, if the skin or flesh is consumed it can be fatal to humans.
When threatened they will puff up like a football to deter predators.
