Gammarus Shrimp

Link to Shore Animals

Lift up a rock on a sheltered shore and you will often find a mass of wriggling shrimps beneath. These small crustaceans hide beneath weed or stone when the tide is out, emerging when the water returns to swim about and feed on small bits of organic debris. Males are bigger than females - you will often see a male / female pair swimming about together when they are mating. A similar species is found amongst washed up weed on sandy beaches - called sandhoppers these white shrimps will spring into the air to avoid capture.
