Family Actinodendronidae
updated Aug 10
Where seen? This bizarre and scary-looking anemone is sometimes seen on our shores among coral rubble. Dr Daphne shared that there is only one species in this genus, and it is known from the western rim of the Pacific.

Features: 10-20cm in diameter. It has about 12 long fat cylindrical tentacles that taper at the tips, and below these, another ring of much shorter, slimmer tentacles. The tentacles are studded with bumps. Those seen were a uniform dark brown to black. One seen on Beting Bronok curled up into a ball when a little fish swam into it.
