clustered bead ascidians Eudistoma sp.* Family Polycitoridae updated Mar 2020 Where seen? These clusters of yellow blobs are commonly seen on many of our Northern shores, on hard surfaces near the mid-water mark. Features: Each blob about 1cm across, somewhat columnar with a rounded top. Clusters of blobs form on boulders and larger rocks, usually near the base and under overhangs. Also on jetty pilings. Blue-dot margined flatworms have been seen near them, appearing to envelope a similarly shaped object. Do these worms eat the ascidian? |
