Surface of carapace smooth, ridges low but distinct; front with 6 equal-sized, rounded lobes. Color: dark to olive green overall.
Also caught by nets (Ref. 343). This species possess toxins but in low toxicities, and are therefore considered as a toxin-free crab (Ref. 130560). Found along the neritic zone (Ref. 97241). Inhabits shallow non-reef habitat with soft substrates (Ref. 106854), and intertidal mudflats (Ref. 128960). Estuarine (Ref. 106854). Prefers areas near mangroves, on mangrove swamps per se (Ref. 8752) or with muddy-rocky substrates (Ref. 343) in intertidal platforms (Ref. 8752). Also found in reef areas. A free-living predatory carnivore (Refs. 97241, 128960). Feeds mainly on slow-moving invertebrates colonizing mangrove swamps; also a scavenger (Ref. 8752).
