If we are to assume that the animal in the Kyoto photographs is Architeuthis and it shows unusual features, such as the keel, can a particular species be determined? Is it, perhaps a member of its own species? Based on Dr. O'Shea's writings elsewhere on TONMO, any distinction between A. clarkei, A. kirkii and A. japonica are illusory -- there is only A. dux. Any comments?
Hmmmm - I've just been quoted. Neither morphological nor genetic grounds exist for recognising multiple species of
Architeuthis, at least throughout the North and South Atlantic, and South Pacific, but we haven't been able to secure comparative material from the central and northern Pacific. With this in mind we recognise a single Atlantic/South Pacific species,
A. dux being the first described. The Japanese fauna is interesting in that many species are common to New Zealand, in addition to a number of otherwise very closely related species common to these two regions (without recognised [STRESS
recognised] taxa known from intermediate locals) (The New Zealand and Japanese cephalopod faunas being amongst the best known/described thus far; it could be an artefact of monographic revision). Nevertheless, there would appear to be a clear biogeographic link between the two regions; because of this I would be surprised if a separate species of
Architeuthis occured off Japan. Then again, one thing that never ceases to surprise me when it comes to cephalopods is
how often I end up being surprised.
A. japonica and
A. clarkei are probably synonyms of
A. dux, but until these Pacific forms are revised then we'll not know for sure.
As for coming to New Zealand and helping out, well, let me think about this.

OK, you're on! You tell me what you'd like to do and I'm sure we'll be able to find something.
