Random Quote

Few theologians would care to pursue their research to its logical conclusion and finally assert, as did Thomas Paine, that the biblical account of Jesus has every mark of fraud and imposition stamped upon the face of it.

[George H. Smith, from Atheism: The Case Against God, chapter 2, The Concept of God]

Wow, that's so awe inspiring I could almost pray to it!

Though I think I noticed a few defective cromatophores maybe you should send it back to the manufacturer, er designer...

I suppose I can see an eye, but I do not understand the rest of this... thing. Was it submitted to some kind of... compression ?

Nat, the arms are folded back over the shell-like egg case. You can glimpse part of the white wall of the case behind the eye.

"I do not understand the rest of this... thing."

Seems you're not alone... e.g., it really is an octopus, but the egg case looks a lot like a nautilus shell. More about it at The Cephalopod Page:

I misread the caption as "argonauta medusa" the first time.

Wowzers!
A mother argonaut!
Do the females die after the eggs hatch, like other octopi?
