 Where 
            seen? These 
            rounded blob-shaped animals are commonly seen on our Northern shores .
 
 Features: Colony 
            about 5-10cm in diameter. Rubbery blobs forming on hard surfaces or 
            on stones near 
            the mid-water mark. In various shades 
            of black, red, yellow, brown and beige.
 
 These blob ascidians look like the ones that are sometimes used by 
            some sponge crabs for camouflage and protection.
