Yellow Boxfish
Yellow Boxfish are very popular & photogenic reef fish in the Indo-Pacific region and can be found in other parts of the world, as well. They swim slowy and they are brightly coloured, so therefore could be an easy target for predators. However, their bright colouration is a sign to potential predators that they contain strong toxins.
