About
Actinia equina is a sea anemone of the family Actiniidae, common on rocky shores around Japan. The name is used because Japanese animals were long treated as the same species as those from Britain, western Europe, the Mediterranean and West Africa, but Japanese populations may be a separate species (Wikipedia). Adults bear 96 and up to 192 tentacles arranged in six circles. When the tide falls and the tentacles are withdrawn, it becomes a red-brown blob about 5 cm across, like a Japanese pickled plum. Blue beads called acrorhagi, packed with stinging cells, ring the top of the column and are used to fight neighbours for space. Adapted to the intertidal zone, it tolerates some heat and drying and can live in estuaries where salinity varies. It reproduces by releasing small, asexually produced young from its mouth. It is considered easy to keep, and one individual in Britain lived nearly 60 years in captivity. In Japan, shore-collected specimens are sold by marine livestock dealers.
