General Description

Rostrum triangular, laterally armed with five pairs of teeth, undifferentiated supraocular spine, unarmed submedian gastric carina anteriorly flexed towards the midline; uropodal exopod with a transverse suture, pleurobranchs present above pereopods 2-4 and sometimes 5, male pleopod 1 present, two-articled, with the second article triangular and bearing a thumb-like appendix interna.

Biology

Mud shrimps build permanent burrows in firm sediment. Some large species, and there are many in the tropics, burrow up to three metres deep. It is presumed that this species lives in burrows but it has been collected only with samples from muddy sediments. Like many mud burrowers, the shrimp is white or pale cream.

Habitat

Intertidal, 2-25 m depth.
