Gigantothermy • Sometimes called ectothermic homeothermy) • Large, bulky ectothermic animals are more easily able to maintain a constant, relatively high body temperature than smaller animals by virtue of their greater volume to surface area ratio.
My skin turned green and scaly, I went from endo - to ectothermic and, in that life-affirming and horrifying moment every boy remembers forever, laid my first batch of soft, mucousy eggs.

I had such a wonderful time imagining you applying an ice cold stethoscope as only a ectothermic saurian can.
Like other cold-adapted reptiles and other ectothermic vertebrates, they exhibit behavioural hyperexcitability when chilled (that is, they suddenly become apparently alert and vigorous), and (counter-intuitively) increase the number of movements they make when exposed to really low temperatures.
