Where seen? These white blobs are sometimes seen on some of our shores. On coral rubble or seagrasses and seaweeds.

Features: Irregular blobs 2-5cm across. Usually white or pinkish. Smooth and slippery looking when out of water. When submerged, tiny regularly-spaced holes can be seen. Some slightly larger holes have short transparent cones with white stripes.
