Ceratosoma sp. 6
Khao Lak, Thailand
This Ceratosoma species is still undescribed and has been classified as a new subspecies. The photo was taken at Khao Na Yak in
Khao Lak/Thailand and is the first record so far!
Rudie H. Kuiter:
"This amazing looking slug shows great resemblance to the Long-nose Filefish 'Oxymonacanthus
longirostris' in its colouration. Is this a case of mimicry? From what we know in other similar cases the slug
would be the model and the fish the mimic, but, as these photos may be the first record of this species,
the model appears to be extremely rare. Was it once common?"
