Economic Importance and Threats
Threats:  Anthropogenic
(The species is threatened by the degradation and loss of wetland habitats through environmental pollution (e.g. oil contamination of intertidal mudflats) reduced river flows and human disturbance (e.g. from off-road vehicles, tourists and hunters). )
Threats:  Natural threats
(The species is also potentially threatened by climate change because it has a geographically bounded distribution: its global distribution is restricted to within c.10o latitude from the polar edge of continent and within which 20-50% of current vegetation type is projected to disappear under doubling of CO2 levels.)

Ecology
Habitat:  Estuarine, Rocky, Sandy, Muddy, Coastal
Trophic Level:  Consumer
Prey:  Carnivorous-tiny crustaceans, molluscs etc washedup on the seashore.
IUCN Status:  Least Concern
