Fourth segment (merus) of larger claw (cheliped) with hook on lower margin; sixth segment (propodus) excavate in gape in male only; last segment (dactylus) with 2 strong teeth in male, simple in female. Tail fan (telson) as wide as long, shorter than uropods. Up to 4.5 cm long.
This small but abundant species is so named because it prefers sandy sediments (unlike other species which prefer deeper muddy bays). The combination of a blade-like lobe on the arm of the larger claw and a squarish telson differentiate this species from Callianassa limosa. The species is an active burrower important in sedimentary nutrient dynamics. It makes a complex burrow and feeds on the sediment it excavates.
Intertidal to shallow subtidal sandflats, often estuarine, depths to 25 m.
Southern temperate oceans, including south-eastern Australia.
Not harmful but a nip from large claws could be painful
