awaiting identification
updated Feb 13

Where seen? This animal is sometimes seen on hard surfaces in shady places (overhang of boulders, under jetties on pilings) on our Northern shores near the mid-water mark, as well as on coral rubble among sponges.

Features:
5-15cm in diameter. Irregular rubbery layers with many tiny well-spaced holes and a few large holes. When in water, inflates into more rounded shapes. In various shades of white, pink, lilac and orange. Out of water, it is deflated and appears to be a 'melted' or slimy layer.
