General Description

Southern Wentletraps are carnivores, feeding on sea anemones. Like other Wentletraps, this species has a purplish saliva, which it may expel when disturbed. Wentletraps are protandric hermaphrodites, meaning they begin life as males then become females as they mature. Eggs are laid in spherical capsules encrusted by sand, which contain more than 100 eggs. Larvae hatch from the eggs as free-swimming larvae into the plankton where they may spend up to a month before settling and becoming adults. The name Wentletrap comes from the Dutch for spiral stairs.


Southern mainland Australia and Tasmania.
