**Red-fin Crab

Scientific name: Perbrinckia enodis

Article (short):
Perbrinckia crabs are a group of tiny stream specialists and P. enodis lives only where cool forest streams run clear. Their small size belies a big role: they shred leaf litter, keep streams flowing, and support fish and insect life - and their survival is threatened as streams get diverted and forests are cleared.

Quick facts

Status (approx.): Critically Endangered / micro-endemic (many Perbrinckia species are CR).

Range: Select freshwater streams in Sri Lanka (very local).

Habitat: Shallow, shaded stream margins and seepage rocks.

Diet: Detritus, algae, small invertebrates.

Lifespan: Several years typical for small freshwater crabs.

Reproduction: Brooded eggs; juveniles require clean, oxygenated water.

Ecological role: Key detritivores, supporting nutrient cycling and stream clarity.

Main threats: Water pollution, stream alteration, forest clearance.
