Elysia crispata question...

December 12, 2001
From: Rich Hunziker

I recently had an accident with my Elysia crispata mine and I needed some urgent info ....

It decided to explore my protein skimmer overflow box and crawled in through the inlet box. Well, needless to say when I got home that night the skimmer was making an awful noise. What had happened is the slug was sucked into the Rio pump and had actually jammed the blades of the motor. I immediately powered it off and within a few seconds my little buddy was crawling out onto my hand. I placed her in a safe part of the tank to determine the damage. A few days have gone by now and she appears to be somewhat ok. (As much as can be expected) She is missing half of her frilly section of her body, half of an antennae, and a smaller section out of what I would call her lip/mouth area. She is still active which is encouraging, but I am concerned about any
pain or suffering.
Will she recover?
Thanks,
Rich Hunziker

Dear Rich,
To stop confusion I changed the name in your message from Tridachia crispata which is a name no longer in use.

We don't know an awful lot about regeneration in opisthobranchs other than that they seem to be able to regrow quite significant amounts of their body. I suspect your skimmer saboteur will make a complete recovery. I'm afraid I can give you no indication on pain and suffering. Clearly all animals respond to stimuli, and damage no doubt is a major source of stimuli - but whether their little 'brains' feel pain & suffering as we understand it I have no idea. Considering what it has survived, however, I reckon it deserves a chance to recover.
Best wishes,
Bill Rudman.
