Ceratosoma gracillimum

"This name is used because there seems to be a complete absence of a mantle brim (= sharp mantle margin) between the head and the lateral lobes, which is the diagnostic feature for Ceratosoma gracillimum. This certainly appears to be the case on the animal’s right side, but it cannot be checked on the left side because the rhinophore is blocking the view. However, given the locality, this might be just another colour form of Ceratosoma trilobatum."
