á

Eurycarcinus natalensis (Krauss, 1843)

Family: Xanthidae

This is a beautifully colored mangrove crab, also a predator with strong claws.

Zone: Edge of Avicennia marina zone to creek edge, more common in muddy regions (Gillikin, 2000). Macnae (1968) found this species from the seaward fringe into the Rhizophora and Bruguiera forests.

Habitat: Around the base of trees and roots, utilizes cervices in mud (Dahdouh-Guebas et al., 1999; Gillikin, 2000)

Food: Ambush predator, carnivorous, eating mostly other crustaceans (Dahdouh-Guebas et al., 1999).

Ecological notes: Hides in mud to ambush predators.

Distinguishing characteristics: Purple color, smooth carapace, claw tips white, a single central notch on the frontal margin. Carapace width about 4 cm.

Geographical range: Kenya (Dahdouh-Guebas et al., 1999), Mozambique (Clark and Paula, 2003), ???
