Blackback Land Crab (Gecarcinus Lateralis)

The Blackback Land Crab (Gecarcinus Lateralis), locally known as Touloulou, is a burrowing species found across coastal and inland zones of Dominica. It favours sandy soils near the coastline but also thrives in agricultural edges and secondary forests. Populations are regularly seen near the Cabrits National Park, the Batali Beach, and coastal communities such as Pointe Michel and Soufrière.

Ecological and Cultural Significance

This crab is a contributor to Dominica’s Biodiversity, recycling plant material and organic debris. Its striking coloration makes it easily identifiable among Dominican land crabs. For local communities, crab hunting happens occasionally and linked to food traditions tied to Dominica’s Culinary Heritage, though less commonly than the Blue Land Crab (Cardisoma guanhumi). The species supports wildlife, providing prey for herons like the Yellow-crowned Night Heron (Kwabyé). Conservation measures under the Forestry and Wildlife Act safeguard its role in our ecosystems.

Sightings and Best Viewing Areas

Best viewed during the rainy season, Gecarcinus lateralis emerges in large numbers after rainfall. Walkers on the Waitukubuli National Trail (WNT) often encounter them crossing paths. Coastal stretches near Scotts Head and inland nature sites such as the Syndicate Nature Trail may provide opportunities for sightings. Eco-tour operators focusing on marine conservation frequently highlight this species to illustrate the link between land and sea in Dominica’s environment.
