About Scylla olivacea (Herbst, 1796)
Scylla olivacea is commonly called the orange mud crab, a commercially important mangrove crab species belonging to the genus Scylla. It is one of multiple crab species that are referred to as mud crab. Its range covers mangrove habitats stretching from Southeast Asia to Pakistan, and from Japan to northern Australia, where the species is locally known as Wenlock Red. Like other species in the genus Scylla, Scylla olivacea is widely farmed in aquaculture that relies on wild-caught broodstock. This species can be distinguished from other Scylla species by two key features: it has blunted spines on the dorsal distal corner of the claw palm, the propodus, and it has rounded frontal lobe spines with shallow gaps between them, located between the eyes.
