Description
Also known as Tunicates, Sea Squirts, Colonial ascidians, Compound ascidians, Robust Tunicate, Golden Sea Squirt, Soft Sea Squirt, Urn Sea Squirt and Urn Ascidian.
Found in groups in shallow sheltered water growing on dead coral.
They feed on suspended plankton and detritus.
Length 2.5cm
Depth - 1-20m
Widespread Indo-Pacific
These urn shaped ascidians have numerous oral siphons.
Often confused with Didemnum molle which has numerous and minute oral siphons.
They vary in colour from white, orange to bright green.
The green colour inside is the result of being inhabited by minute blue/green algae.
The Egyptian sea star - Gomophia egyptiaca and the Sea Snail - Gyrineum gyrinum prey upon this sea squirt.
