Tag: Hairy Mushroom Anemone (Rhodactis indosinensis)

This identification is very tentative at the moment and is by no means definitive.

This species almost certainly belongs within one of either the Discocoma or Rhodactis genus, with the Hairy Mushroom Anemone (Rhodactis indosinensis) being a possible candidate.

Although it is proving very difficult to identify with a reasonable degree of certainty, this is a very abundant species in local waters, particularly the deeper offshore sites such as Sail Rock where it forms large colonies over large expanses of the rock face.

As with many of its relatives, this species possesses stinging tentacles which are used to immobilize its favoured prey of small fish and crustaceans.

These tentacles are also capable of inflicting nasty stings on unsuspecting divers who accidentally brush against them, resulting in inflammation, irritation and blisters, which may be present for a few weeks.

Evidence of the nasty sting that can be inflicted by members of the Cnidaria family which includes Jellyfish, Corals and Sea Anemones.

In this photograph of the species i've tentatively identified as the Hairy Mushroom Anemone (Rhodactis Indosinensis), the pedal disk or foot can be seen attached to a red encrusting sponge, possibly Clathria Mima or Monanchora Barbadensis.

Although tentatively identified as the Hairy Mushroom Anemone (Rhodactis Indosinensis), i am far from certain that this is correct.
