Why is misleading to say that ectotherms are cold blooded?

Saying that ectotherms are "cold-blooded" is misleading because it implies that their body temperature is always low, when in fact it varies with environmental conditions. Ectotherms regulate their temperature behaviorally by basking in the sun or seeking shade, allowing them to be active in a range of temperatures. Additionally, their metabolic rates can change significantly based on their surroundings, meaning they can be quite active in warmer environments. Thus, the term oversimplifies the complexity of their physiological responses to temperature.
