GENERAL CHARACTERISTICS: The Hell’s Fire Anemone is poorly described. It looks more like a coral than and anemone. The color of  A. plumosum can be light yellowish-green, tan, brown, light green or gray. They have an oral disc that is drawn out into branched tentacles tipped with white swellings resembling globular spheres. Their tree like shape is unique in comparison to other anemones. Size: up to 12″ (30 cm).

DISTRIBUTION/HABITAT: Indo-Pacific on coral rich slopes and drop offs with coral gravel, or in shallow sandy and muddy areas. They bury their foot and body into the substrate and adhere their foot to hard surfaces underneath, having only their oral disc and tentacles emerging. When disturbed they can retract their entire body into the sand and be virtually invisible.

REMARKS: The sting from these anemones can damage and even kill other corals and fish. They use their very powerful and venomous nematocyst found in their tentacles to sting and deflect any possible threats or attacks, as well as for capturing prey. In humans the stings can cause ulcers at the site which last for months.
