Cunjevoi, Pyura stolonifera, forms large mats over intertidal platforms (above at Shelley Beach, Ballina). Broken off clumps are often found washed up on Main Beach after storms. Pyura stolonifera has a hard tunic. Its two siphons are very close together and are tightly closed at low tide. Cunjevoi is often covered with algae.

It is traditional eaten by people in Chile and by Aboriginal people. It is used by fishermen as bait, and loggerhead turtles are often seen eating cunjevoi.
