Crustacean Castanets
Our garden pond is currently full of these little Cypris sp., a.k.a. seed shrimps, that belong to a subclass of crustaceans called ostracods. Each animal resembles a water flea enclosed within a pair of hinged shells. When they’re swimming they look like animated castanets (see video clip), when they’re at rest they look like a minute bean.
