Ectotherm


Ectotherm (Dyeing Dart Frog)

Ectotherms are any cold-blooded animal that depend on external sources to regulate body temperature. Animals of this category include fishes, amphibians, reptiles, and invertebrates. They tend to not need as much food as endotherms of their same size, but they don't do well with cold surroundings. They stick to places with constant temperatures, like regions of the abyssal ocean; but others in harsher climates are forced to seek external sources of heat or shelter from heat.
