Ectotherm Guide, Meaning , Facts, Information and Description
An
ectotherm is an
animal that does not control its body temperature through
metabolic regulation. Ectotherms depend largely on external sources of heat, such as
solar radiation. As the environmental temperature increases, the animal's metabolic rate will increase. Lizards, fish, and
amphibians are examples of ectotherms.
Whereas an
endotherm will use up to 98% of its energy for heat production, an ectotherm has all this energy available for activity, growth, repair and reproduction.
