Ghost shrimps, sometimes called "Bass yabbies", "ghost nippers" or "one-armed bandits" in Victoria, dig deep permanent burrows on mud flats intertidally and on deeper sediment. In places like Western Port, the burrows can be found alongside seagrasses. Each burrow has two openings, one funnel-shaped down which water is drawn for ventilation, and another with a volcano built of mud excavated by the shrimp and dumped outside. This species is extremely common on muddy sediments in Port Phillip Bay.
Subtidal muddy sediments to 100 m depth.
Southern temperate oceans, including south-eastern Australia.
Not harmful but a nip from large claws could be painful
