Common prawns are found in rockpools and shallow waters down to around 40m deep, normally hiding in crevices or under stones. Common prawns are scavengers and will eat anything they find, from decaying seaweed to dead mussels. There is a very similar, closely related species also found in rockpools called the rockpool shrimp.What to look for
A large shrimp with a translucent body with brownish-red tiger stripes along the length. It has large eyes separated by a serrated rostrum. Its walking legs are banded with reddish-brown and bright yellow and it has very long brown antennae. It is virtually identical to the rockpool shrimp (Palaemon elegans); they can be told apart by the number of teeth on the rostrum.Where to find
Found on rocky shores all around UK coasts.Habitats
