Minuca Burgersi

A small fiddler crab of intertidal mudflats, Minuca Burgersi, lives in shallow burrows on exposed, fine-silt flats. On Dominica, it is abundant on the large mudflat just south of the Indian River in Portsmouth, often occurring by the thousands alongside Minuca vocator. Males sometimes build small “chimneys” at burrow entrances. Nearby visitor points include Prince Rupert Bay and the Cabrits Marine Reserve.

Ecological and Cultural Significance

By reworking surface sediments and grazing organic films, this species helps maintain productive shorelines that support marine ecosystems. Dense colonies provide food for wading birds and small estuarine fishes, contributing to Dominica Wildlife and biodiversity. The mudflats that fringe mangrove swamps benefit from this constant aeration and nutrient cycling.

Sightings and Best Viewing Areas

Plan visits for low tide on the south-of-Indian River mudflat, when burrow openings and surface activity peak. Quiet observation from the edge of the flat reveals waves of feeding and signaling males raising the enlarged claw. Nature walks that also take in Indian River Tourism Facility and nearby coastal viewpoints offer good chances to observe this species without disturbing the habitat.
