Miniature crayfish

Miniature crayfish

After months drifting about in ocean currents, crayfish larvae transform into a puerulus phase, which resembles a miniature transparent crayfish. Fuelled by fat stored in their bodies, thumb-sized pueruli swim back to the coast and undergo a further metamorphosis into juvenile crayfish. Four pueruli are shown here in a glass Petri dish.
