Circular False Spider Crab
  • Ecology, Habitat & Location
    • Ecological Notes :

      Habitats :
      Mudflats, Marine
      Distribution :
      So far known only from sublittoral mudflats off Tuas, Singapore, in the western Straits of Johore. Likely to be found in similar habitats in the Straits of Johore.
  • Conservation
    • Trends & Threats :
      Loss, degradation or modification of its sublittoral mudflat habitat from pollution and coastal or other developments along the Straits of Johor.
      Scientific Interest & Potential Value :
      This is the most recently discovered species of crab from Singapore, having been described only in February 2007.
      Conservation Notes :
      This species is known from only two female specimens so far; by virtue of this and how little is known about its habits. It is tentatively regarded as Critically Endangered. It is possible that the species might actually be more common, but its small size and probably cryptic habits have kept it hidden and unknown thus far. Control of coastal and marine pollution and retention of muddy bottom sublittoral habitats are recommended.
