• Question from:Wood

If you cut off an octopus' tentacle (arm ?), does it grow back ? And if it does, is the new arm fully functional ?

Hi Wood,

Sorry for taking so long to reply!

Apparently, an octopus' arm won't grow back, but squid and cuttlefish regeneration seems to be more documented.

Hope this helps,

Carlos.
