  Family Name : Pilumnidae

  Taxonomic Group : Invertebrates (Crustacean, Crab and Prawn)

  Common Names : Feather Star Crab

Feather Star Crab
  • Ecology, Habitat & Location
    • Ecological Notes :
      Obligate commensals of feather stars (Crinoidea) in coral reefs with relatively clear and unpolluted waters.
      Habitats :
      Coral Reef, Marine
      Distribution :
      Found throughout Southeast Asia and northern Australia. Two species occur in Singapore: H. albolineata Adams & White, 1849, and H. longipes Lanchester, 1900.
  • Conservation
    • Trends & Threats :
      As obligate commensals of feather stars, the survival of these species is directly linked to the conservation of their hosts, and the coral reefs which they inhabit. The destruction of our reefs, in part due to heavy siltation and dumping, may have already critically depleted local populations of feather stars, which are now very rare in Singapore waters.
      Scientific Interest & Potential Value :
      Harrovia longipes was first collected and named from Singapore in 1900, but it was not regarded as valid for several decades. Only recently has the evidence been obtained to recognise this very distinctive, coral reef species.
      Conservation Notes :
      The continued health and conservation of the coral reefs is necessary to conserve both the crab and the feather star host.
