This was our most commonly observed nudibranch during the 2015 trip. Multiple individuals could be seen on every dive in all locations. They were usually in plain sight on tops of rocks or sponges. Their chemical defenses must be effective. There were less abundant, but still common on subsequent trips.
An odd color pattern, with the marginal colors meeting in the middle.
Genital opening shown as orange patch beneath the rightmost mantle undulation.
It is uncertain what caused the margin on the individual below to be so ragged.
