About
Heterodactyla hemprichii is a sea anemone of the family Thalassianthidae. It is widespread on reefs from the Red Sea across the Indian and Pacific Oceans; in Japan it occurs in shallow water to 10 m from the Kii Peninsula to Okinawa, with Kushimoto as its northern limit (Kushimoto Marine Park, Ugui Visitor Center). The disc-shaped oral disc is densely covered with short, tree-like branched brown tentacles, and just inside the margin sits a ring of grape-like tentacles coloured purple and green. These are sticky tentacles with strong adhesive power. The oral disc reaches 20-30 cm across. Clownfish do not live in it, but commensal anemone shrimps may (Wikipedia, Reeflex). Anemones of this family contain sodium-channel toxins lethal to crabs (Wikipedia). The adhesive anemone Cryptodendrum adhaesivum, also on this site, belongs to the same family. Reeflex notes that no successful long-term keeping has yet been reported, so it is for experienced keepers only. In Japan it reaches specialist shops only occasionally.
