C. intestinalis is a solitary, translucent ascidian that can have a pale yellow or pale green hue. If individuals are not fouled by algae or invertebrates, ten muscle bands that run the length of the body are visible, and pale orange internal organs are seen through the translucent body. The brachial siphon has eight lobes and the atrial siphon has six lobes. Both siphons may have yellow or orange margins.

C. intestinalis can quickly form dense aggregations, which can smother and eventually exclude other fouling species and exert heavy grazing pressure on the local phytoplankton and bacterial communities (Peterson and RiisgŒrd, 1992;Lambert and Lambert, 1998;RiisgŒrd et al., 1998;Blum et al., 2007;Petersen, 2007). In Tasmania, C. intestinalis was found to harbour the amoeba, Neoparamoeba pemaquidensis, which is responsible for amoebic gill disease in farmed salmon (Tan et al., 2002).
