Common Prawn

Palaemon serratus

Common Prawn (Palaemon serratus)

The Common Prawn has large eyes and a translucent body with yellow, brown or reddish stripes. It has an elongate body with a fan-shaped telson (last segment, or appendage of the last segment of the abdomen). It has a large upturned rostrum with 6-7 dorsal teeth and 4-5 ventral teeth. The first two pairs of walking legs bear claws, and have red, blue and yellowish banding. It can move very quickly, and is a very inquisitive creature. Length up to 11cm.

It is a ominvore and it will eat virtually anything from dead animal life, to hunting other invertebrates, and to consuming plant material.

Found on the upper to lower shore, in rockpools, amongst seaweeds and under rocks and boulders. Our commonest prawn, it is widespread throughout. Prawns are a valuable food source, and are of extreme commercial interest.

    1. Thank you, Belinda 🙂 These are quite tricky, and are virtually impossible to photograph in their natural environment. I had to catch one first, place it in a plastic dish and hope it would keep still, which it did, thankfully.
