Blue-grey with green and orange spots, and it will swim if it has to.
A dorid to about 6 cm, pale blue-grey with a dense scatter of small green-yellow spots over the back and a line of larger orange-red spots around the mantle margin. The rhinophores are orange and the gill plume is white with orange or maroon edging. The mantle is thin and the skirt is proportionally wide.
One of the few chromodorids that will leave the bottom: pressed hard, it lifts off and swims with slow lateral flexions of the whole body, which is uncommon in the family and worth not provoking for the sake of a photograph. It tolerates silty, sheltered water better than most of its relatives and is one of the nudibranchs found on the shallowest, muddiest parts of a muck site rather than out on clean rubble. Feeds on sponges. Recorded from about a metre to 25 m, and widespread from the Red Sea to the western Pacific.
Ratings are per location: 1 means found on most dives that look for it, 5 means a handful of records. Where enough dives have been logged the figure is calculated from them; otherwise it is an editorial estimate, and says so. We publish habitat and destination, not the dive site.
