Finding myself with some free time to browse for cool cephalopod videos, I found this clip of an octopus taking shelter in some post-party refuse:
A few clicks later, and I found this cute fella:
Cuteness aside, though, it’s a bit depressing to see videos of animals living in our trash.
Thanks for reading!

Poor ecological management aside, I love the colour change of the second guy as he squeezes out! Are octopus chromatophores mechanoreceptive as well as neurally controlled? I remember seeing a video of a dead cuttlefish responding to touch.
As far as I know, chromatophores are only neurally and possibly hormonally controlled, although I’d expect that direct pressure could deform the chromatophore, making it appear to expand or contract.
A “dead” cuttlefish could respond to touch via a neural mechanism (via a skin -> ganglia -> skin loop, or an even simpler mechanism,) assuming it hadn’t been dead for too long and the peripheral nervous system were still alive and kicking.
Consider it recycling. If nature is getting good use out of our trash, at least something good is coming out of it!
I’m pretty sure we’re a net drain, though.
You know how I feel about “coconut octopus” (http://arthropoda.southernfriedscience.com/?p=405), but beer octopus is cool in my book.
