Comment from Scott Johnson on photo #31970
Odd color, but I think the two lobes per side make this C. tenue.

Comment from Richard Willan on photo #7651
Probably a juvenile individual in which the first pair of lobes are only weakly developed.

Comment from Richard Willan on photo #5303
A juvenile individual with its gills retracted. Note the two pairs of lateral processes.

Similar Species

Ceratosoma gracillimum can be distinguished externally by the complete absence of the mantle edge between the head and the well-developed lateral lobes on each side.

Ceratosoma trilobatum has the mantle edge, edged in purple, between the head and the lateral lobes. Both species have a similar range of colour variations, as does Ceratosoma tenue, but they differ from each other externally by the lack of a mantle edge in Ceratosoma gracillimum and the extra pair of small lateral lobes in Ceratosoma tenue.
