Despite the fact that I am evolutionarily quite distant from octopuses, I also have a most precious arm which I endeavour to keep safe and to prevent it from getting damaged or bitten off by a predator.

Male octopuses have a favourite arm that they mostly use for sex

The third right arm of male octopuses has a specialised role in mating, and the creatures take extra care to avoid damaging it or losing it to a predator

@Spoon man, I hope that Haruki asked for consent first
@dharmadan you 'raise' a very important question here. I sincerely hope that this is not an example of octobuse - or should that be 'octabuse', I can never remember.
@Spoon In the interests of harmonious cephalopod / human relations, I did think it was worth running it up the flagpole. It can be a sensitive topic.

@dharmadan I am in complete agreement here and I am sure you will recognise that despite the evolutionary gulf there are certain inalienable similarities.

For instance, whilst the octopus has no brain, humans, mostly, have one, but don't use it.

@Spoon I'm reading Adrian Tchaikovsky's Children of Ruin, one of tha major themes of which is the accelerated and manipulated evolution of octopuses on an otherwise empty planet with no local predators. It's pretty fascinating stuff.
@jonlawrence @Spoon The Mountain in the Sea" (Ray Nayler) is also a good read. #goodread https://en.wikipedia.org/wiki/The_Mountain_in_the_Sea

@dharmadan @Spoon ooh, that looks great. thanks!

@jonlawrence

It's fabulous. I also highly recommend it.

@Spoon well, tbf

I am evolutionarily quite distant from octopuses

most octopuddings claim this, in social circles, to better blend in

@MsDropbear42

I have never thought of octopus in a blender. I'll have to try it now.
