General Description

Body very flat and round, head inset into the first body segment with a pair of kidney shaped eyes on top. Body with prominent lateral lobes on pereonite 6. The first legs are a pair of solid claws. Up to 7 mm long.

Biology

Serolina minuta was described from specimens collected from Bass Strait, off the entrance to Port Phillip Bay in 1874 by the "Challenger" expedition. Sand skaters use their discoid shape and camouflage to swim and walk about invisibly on the surface of sand in marine environments. They feed on the organic matter found in the sand.
