These are very common sand crabs, locally represented by two species, D. myctiroides and D. wichmanni. They are easily recognised by the row of silky hairs transversing their abdomens which they use to absorb water from the wet sand. They are detrital feeders, sifting the sand for organic matter. D. wichmanni is the smaller (body up to 1 cm diameter) and more common species, preferring sandier areas, not wandering far from its holes. D. myctiroides however (body up to 1.5cm diameter), inhabits muddier banks, often moving around in large groups at low tide, hence its common name.
