Clavelina robusta

Clavelina robusta is a species of tunicate (sea squirt), in the genus Clavelina (the "little bottles"). Like all ascidians, these sessile animals are filter feeders.

Description[edit]

This species frequently occurs in dense clusters. It has large 2-4 cm cylindrical zooids. They generally range from black to dark blue to gray in colour, with individual zooids having fluorescent green, yellow, or white rings around both siphons.[2] The external cover has a firm basal matrix, and is somewhat transparent and soft.[3]

Distribution[edit]

Clavelina robusta is found, often in large colonies,[4] in the Western Pacific, Australia, Indonesia, the Philippines, Japan, and the Solomon Islands. [2]
