(Quoy & Gaimard, 1834)
Sea tulips, scientific name Pyura spinifera, are sessile ascidians that live in coastal waters at depths of up to 80 m (260 feet). Like all ascidians, sea tulips are filter feeders. Their common name comes from their appearance - that of a knobbly 'bulb' or flower attached to a long stalk. Sea tulips come in a variety of colours, including white, pink, yellow, orange, and purple. The coloration of sea tulips depends upon their association with a symbiotic sponge that covers their surface.
Despite their common name, sea tulips are animals and not plants.
