Insight: Fairy Shrimp (Chirocephalus diaphanus), a primitive gill-footed crustacean, inhabit seasonal pools and ruts often created by farm animals and vehicles. They swim around on their backs propelled by eleven pairs of constantly paddling legs.
The females carry their eggs in an abdominal pouch. The eggs are then released onto the muddy bottom of the pools where they remain dormant during the dry season only hatching once the water returns.
These invertebrates are difficult to locate because they spend much of their adult life hidden in mud with just their eyes protruding and are consequently probably under-recorded in the UK. One established colony is on Salisbury Plain where the species has colonised the water-filled ruts left by tanks during military training.
