Distinguishing features

A moderately-sized sand-dwelling anemone with thick tentacles that are generally smooth on upper and lower surfaces and have side branches.

Megalactis griffithsi is known from the Great Barrier Reef. The Lizard Island specimens look similar to those identified as Megalactis hemprichii from the Philippines and Indonesia. It is not clear which name should apply to the Lizard Island specimens. Rowlett (2020) considers them synonymous with the latter having priority.
