Banded coral shrimp (Stenopus hispidus). Even though this species of decapod crustacean looks like a shrimp and has 'shrimp' in it name, it is not considered to be a true shrimp. It is considered to be a decapod, which is a group of crustaceans. The Banded coral shrimps body is covered in spines, which are used as a defence mechanism and like other decapods they use their tail to escape backwards. This is known as the caridoid escape reaction or lobstering. They also clean other fish of parasites. Photographed in Lembeh Strait, North Sulawesi, Indonesia.
