Brief Summary

Read full entry


This sand hopper spends the day buried in the sand at depths of 10-30 cm, well above the high water mark. It emerges at night to feed on decaying seaweed and other vegetation along the strandline (2). Adults spend the winter in a dormant state above the spring tide high water mark, buried in the substrate at depths of up to 50cm (2). Burrowing into sand means that the sand hopper escapes desiccation (2). Juveniles are unable to burrow, so they retreat to recently deposited seaweed instead, where humidity is relatively high (2). Like all crustaceans, the sand hopper's reproduction is tied closely to the moult cycle. Adults form pairs and mate after the female moults; most reproductive activity takes place between May and August. The female carries the fertilised eggs around in a brood pouch. Juveniles reach maturity by autumn, but do not breed until the summer of the following year (2). Females live for around 18 months, and die during their second winter. Males on average live to around 21 months, dying after the females (2).
