Hell's Fire Anemone

Actinodendron plumosum

Known as garaban in Philippines, the Hell's Fire Anemone Actinodendron plumosum looks more like a coral, but is actually a burrowing anemone. They bury their foot and body in the sand with only their oral disc and tentacles emerging. When disturbed they can retract their entire body into the sand and be virtually invisible. The Hell's Fire Anemone is one of the 'stinging sea anemones' in the Actinodendronidae family.

Habitat:
The garaban, or hell’s fire sea anemone (Actinodendron plumosum), is endemic to the seas of the Indo-Pacific, sometimes known as the Indo-West Pacific, a biogeographic region comprising the tropical waters of the Indian Ocean, the western and central Pacific Ocean, and those connecting them in Indonesia.
