| | | Slug needs a name
I know it is a Black Slug but it would like more of a name than that. Photographed both sides as I believe the breathing hole is important in identification.  
Thanks in anticipation of somebody giving the ID for it.

He looks like a Derek to me ... yup, definitely a Derek! My question is ... how will you recognize him in a crowd? |

If it's Arion ater.. if you give him/her a gentle (gentle) poke with your finger, he'll crunch up to a surprisingly small hunched shape, with all the strange wrinkles on his back showing. And keep watching.. because then he'll actually start wiggling from side to side. I only found this out very recently and can't believe I've never noticed before. But then I only found an enthusiasm for slugs recently. And I'm losing it since they started eating my plants. No, I rather like them really. |

Interesting observation you have made about them not only hunching up but wiggling from side to side. It must be a reaction to put a predator off.

The swaying and twisting motion is also a good identification feature - only Arion ater (and its close relative Arion rufus (or Arion ater subspecies rufus, according to some people) can do it.
There are a couple of other large Arion, the Lusitanian Slug A. lusitanicus (often red or dark brown) and the Durham Slug A. flagellus (stripey when young, often green or greyish as adult, but sometimes brown or black; but always opaque creamy white underneath, whereas ater is usually black or dark grey) but they don't show the swaying rocking reflex when disturbed.
So the behaviour can be really useful if you want to name your beast.
You're also right about the breathing hole - it's toward the front of the mantle in round-back slugs, Arion, and toward the back in keeled slugs like Limax and Deroceras.
Cheers
