sea squirt Polycarpa sp.* Family Styelidae updated Oct 08 Where seen? This blob with a thumb and red stripes is commonly seen our Northern shores. Like some odd disembodied thumbs-up, this animal is usually stuck to a large boulder, jetty pillings and other hard surfaces, near the mid-water mark. Features: About 5cm long, made up of two 'fingers', one shorter and at right angles to the longer larger 'finger'. Usually white with orange or red irregular broad stripes. It is a solitary (not colonial) ascidian. |
