Squids do not have probascis, they have BEAKS. No such creature exists.
Plus, squid have 10 tentacles...Only a couple are present in the picture.
It does show 8 arms, which are the correct number of arms that a squid has. Squids also have a pair of retractile tentacles which are used solely in prey capture, which in the pic would be "invisible" since they would be hidden by the mass of the other limbs. They do indeed have a beak, and a radula, which you would expect from a mollusc. The proboscis... I have absolutely no idea what he was on about (or just "on"). Never mind the fact that there are no freshwater cephs, and according to fossils (of which addmittedly there are few, since cephs are soft-bodied) there never have been, and since cephs date back the the Cambrian, it kinda argues that they can't inhabit freshwater, for one reason or another. In essence, if he'd proposed some sort of large annelid or flatworm detritivore then that would make more sense.
I've spent the last year reviewing literature regarding cephalopods, as well as observing directly specimens and live exhibits, and have come across nothing that would render this theory as even remotely plausable... It's a load of balls.
As I've said before... There is no chance that this exists, especially since it's by "Doc" Sheils...
I'll get the reference to the book tonight. You won't find anything o nthe net about it, I've looked on several occasions to try and verify it, but I'll definitely get that reference tonight!
