Description – Sea slater
The common sea slater is a sea-shore relative of woodlice that can grow up to 3 cm in length (3). It has a flattened, oval-shaped body that is grey to olive in colour and twice as long as it is broad. It has long antennae, seven pairs of walking legs and two projections at the tip of the abdomen, known as uropods. The black eyes are very large and obvious, and are similar to the compound eyes found in insects (4).
Range – Sea slater
This species has a wide distribution in north-west Europe (2). In Britain, it is common on coasts with rocky substrata (4).

The common sea slater is an omnivore, and emerges at night to feed on seaweed and detritus (2). Maturity has been recorded to occur by one year of age, but in most cases breeding will not begin until the sea slater is at least two years old. Breeding takes place in spring and summer. Most individuals only breed once, and have a life span of around two and a half to three years (2).
