Apologies if this is old hat, but does anyone know if this Mesonychoteuthis photo is for real? It's featured in Mark Carwardine's forthcoming book, "Extreme Nature", but I don't know anything more about it.
Sorry mate, it's not, it was built for the Animal Face Off series. However, it's pretty accurate as far as we know, Kat and Dr Steve advised on the anatomy. There was a thread quite recently about this. Somewhere, I'll see if I can find it for you.
That's quite a freaky pic though. I'm just wondering about that eye... is there not a species of squid that has one huge eys and one tiny eye? They both serve purpose of usage at different water depths... or something...
Graeme- Sounding a bit like a fool now!
Yay, another "Cthulhu Cultist"!! Yeah, dude that's kinda what I thought. Azathoth is described as being blind and imbicelic, right? Just basically a huge nuclear mass. Basically Cthulhu looks like my Avatar, because it IS Cthulhu; my plush Cthulhu
If you actually have something to share with us all, and you DO - believe me, you DO, Mr. Cthulhu Avatar - double-posts are fine. None of us make a habit of it or anything like that, but don't worry.
I do this little show, you see...
There is, in fact, a whole family - the Histioteuthidae - with asymmetric eyes. Maybe one of the other species looks more similar to the one you were thinking of? And there are several references on possible functions of the different eyes (just pulled these up on CephBase):
