Are cephalopods exothermic or could they be endothermic?

If they are exothermic, how does a deep ocean ceph regulate it's temperature without sources of heat such as the sun? :sun:

Heya!

As far as I know, molluscs are poikilothermic, that is, they tend to match the temperature of the surrounding water to some extent. I would imagine that they would regulate their body temperature both metabolically and behaviourally. Cold water molluscs here tend not to be any more "sluggish" (GROAN! :P ) than their warm-ish water counterparts. (From what I've seen in a lab).

Them's my two cents... :twocents: Have a good night!
