Picture of Unknown Octopus

Hmmmm. The single row of suckers, obvious low arm-sucker count, and papillose skin are pretty characteristic of southern Pareledone species; it's quite unlike any recognised Graneledone, Thaumeledone or Bentheledone species (we'll leave Megaleledone out of this for the time being), so Pareledone (as a catch-all genus) is probably a good guess. The genus is probably being revised - hence the 'likely Pareledone ' comment by Louise).
Ooohh, that's a neat looking animal. Interesting eyes. The lenses are quite protuberant, and is that luminescence from internal photophores or some weird consequence of the lighting?

Thanks for posting that, Snafflehound.
