Summary

Description

Unlike typical amphipods which have a laterally compressed body, Amphitholina cuniculus is subcylindrical. The head is globular directing the mouthparts forward. These combined with the positioning of the last 2 articles of pereopod 5 and the spination of uropod 3 and the telson are adaptations for its burrowing habits on exposed coasts.

Recorded distribution in Britain and Ireland

A rarely recorded species known from the southwest of the UK, the Isle of Man and southern Ireland.

Global distribution

Only recorded from the Atlantic coast of France outside of the UK.

Habitat

An intertidal and shallow subtidal species found on exposed coasts. Amphitholina cuniculus is associated with the holdfasts of seaweeds, in particular it is found to burrow into the edible seaweed, Alaria esculenta or bladderlocks.
