Description
Prawn is a common name for small aquatic crustaceans with an exoskeleton and ten legs (members of the order of decapods). Found in all types of waterbody throughout the world. Some species live near the shore, hiding in mud or sand, or in crevices of the stones; some others swim about in groups in deep, cold water. They are of grey, brown, white or pink coloured. Some have bands over the body, some have spots. Some prawns are red, yellow, green or blue in colour. Some species can change colour to match the surroundings. Many deep sea species are luminescent (light producers). The size ranges from 2.5 to 30 cm. Prawns are omnivores and essentially scavengers. Some are planktivores and vegetarians. Others feed on aquatic small insects and other animals. The type of food varies according to the developmental stage and species of the prawn.
