Do ectothermic (cold blooded) animals notice temperature around them?
Yes, of course. It’s more necessary for them to notice the temperature around them than it is for an endothermic animal, since they must rely on their environment to regulate their body temperature, whilst endothermic animals regulate their temperature internally. An ectothermic animal must be able to accurately judge the temperature around it – otherwise it might remain lying in the sun until it got heat-stroke, or lying in the shade until it cooled down so much that it became too sluggish to move.
