I love cephalopods (squid, octopuses and cuttlefish). They’re among my favourite marine animals.
When I was studying Marine Biology at The University of Liverpool, we rescued an octopus that ended up in the wet lab with some Nephrops norvegicus (scampi or langoustine).
We kept him for a while, in one of the tanks at the marine lab. I spent a long time just watching him… and the changes in skin colour and texture never ceased to amaze me.
Amazing footage of the cryptic and behavioural colour changes in cephalopods in the second half of this TED talk.
