    Hi there! I was wondering if cephalopods can regenerate lost limbs? I've read a couple of places that certain species (like Vampyroteuthis infernalis) can regenerate limb tips, but I was wondering if this is common among all cephalopods? Also, are there any cephalopods that can wholly regenerate lost limbs?

    I know octopuses regenerate lost limbs I have seem it with my own pets a number of times. i'm pretty sure that squids and cuttles do as well, but i am not 100% on that.

    I have certainly seen squid in my samples which had arms in the process of regeneration and as Dave said octopus can certainly do it!

    Squid and octopus species seem to be capable of complete limb regeneration, in general, though there is certainly likely to be variations across species and groups. I went looking for a reference that was not tucked behind a paywall, and found (among other things) an interesting book chapter on the topic from 1920:

    There's another thread about this over here, with some more good references.
