The Panther Grouper, also known as the Polka-Dot Grouper, is an off-white fish with polka-dots over the entire body. It is found in crevices and swims along the reefs of the Indo-Pacific, where it can attain a size of up to 20" (50 cm). The Panther Grouper camouflage the fish and act as a disrupter by breaking up the body shape so that other fish and would-be predators cannot identify it
