Sea Squirt Polycarpa Order Ascidiacea Solitary ascideans are reef and rocky shore dwellers. They have two openings, one for the inhalent current where plankton-rich water is drawn in, and the other for the exhalent. When squeezed, water shoots out of the exhalent opening, hence their common name. (Length up to 8cm).
