“In general, however, an endotherm sustains maximum energy output more than twice as long as an ectotherm.”

“For two ectotherm animals of the same size, if one has moist skin and the other dry skin, the first will be cooler through evaporation.”

“Within a season, in ectotherm physiological time the amount of ectotherm predation may be relatively unaltered by temperature.”

“Endothermy did evolve from ectothermy, and birds did evolve from dinosaurs, which we know came from ectothermic ancestors sometime in the distant past.”

“Cold-bloodedness, also called Poikilothermy, Ectothermy, or Heterothermy, the state of having a variable body temperature that is usually only slightly higher than the environmental temperature.”

“With regard to the distance traveled before exhaustion, intermittent locomotion can have greater consequences for ectotherms than endotherms.”

“Similarly, some modern ectotherms, chameleons for example, have an erect posture.”

“Ecological studies suggest that today's endotherms generally outcompete ectotherms in their area.”
