Ascidiella scabra

Hairy sea-squirt

   Ascidiella scabra is a solitary ascidian of 2 to 5 cm in length. Its oval body is often attached to sustratum, seaweeds or rocks, by its left side. The cartilaginous test is white, more or less translucent with small reddish spots and small red papillae around both siphons. The atrial siphon is close to the terminal oral siphon.
The hairy sea-squirt lives from low level water to 300 meters deep. It is found in the Atlantic Ocean, the North Sea, the English Channel and the Mediterranean Sea.
