Janthina janthina (Linne, 1758)

This species spends its entire life cycle(holeopelagic) at the oceans surface, attached by
the foot to a raft of mucus covered bubbles. It is carnivorous, preying on pelagic Cnidarians
such as Porpita sp, Velella velella and Physalia sp(Bluebottle). This is the largest and
commonest species found on Australian beaches but has an almost worldwide distribution.

Overgrown with Lepas pectinata


Feeding on Physalia
