Strong Swimmers
Like other cubozoans, Tamoya swims actively using pulsing contractions of a muscular bell and can steer with its complex eyes. It hunts fish and crustaceans.
Stings
The stinging cells of the tentacles cause intense pain, welts and sometimes systemic symptoms. Specimens drift to coasts in some seasons. See Sea Wasp.
Poorly Studied
The biology of this species is not well known compared with its Australian relatives. See Mediterranean Box Jelly.
