Green and ridged like a piece of soft coral, which is the point.
A dorid to about 9 cm, the back a deep green to olive raised into a set of blunt longitudinal ridges and tubercles, edged and picked out in orange, blue and white lines, with a raised horn behind the gill in the manner of Ceratosoma. The combination of the sculpted back and the colour makes it one of the more striking sea slugs in the region, and one of the least like a sea slug at rest — an animal folded down among rubble reads as a fragment of soft coral.
Formerly placed in Ceratosoma, and separated into Miamira on anatomy; both names are in wide use. Feeds on sponges. It is uncommon rather than rare and is one of the finds that makes a rubble slope worth working slowly. Recorded from about 5 to 30 m. The ridges take light badly from directly above — the frame that works puts the strobe low and to one side so the sculpture has shadows in it.
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.
