What a beautiful cephalopod!
And the comments--it really seems odd
That these two-legged freaks
(who have lips, and not beaks?)
Have the nerve to keep up their facade.
It is clear, the superior shapes
Of the cephalopods, to the apes,
Shows superior worth;
We will soon rule the earth
And we'll crush you like so many grapes.

Nice pic.
Hey, question: what is the function of the size of the web between the tentacles of various octupi? It seems to vary between species (yeah, I've been reading this blog too long and seen too many pics) and I'm wondering if it's got to do with adaptation for hunting or camo or something else entirely.

Assuming this is the same species as the one I saw, the picture doesn't do it justice. The colours, especially at night with a flashlight, are brilliant. It was near Puerto la Cruz, Venezuela, shyly trying to keep the marine life encrusted piling between itself and me.
Maybe it's a good thing to have very shy, intelligent beings as overlords.

They're not SHY, they're STEALTHY, you damn collaborator. What are they so desperate to hide, huh?

Smile please.
Here's a happy cephalopod,
