These were exposed in rubble or reef areas at several different dive sites.
The one below happened to be next to a Thecacera picta.
The slight bluish tint on the specimen below makes the ID slightly questionably.
The reproductive opening is visible as an orange spot on the right side of the animal below the mantle margin, between the rhinophores and gills.
