An ectotherm (from the Greek ἐκτός (ektós) "outside" and θερμός (thermós) "heat"), more commonly referred to as a "cold-blooded animal", is an animal in which internal physiological sources of heat are of relatively small or of quite negligible importance in controlling body temperature.
In this article we show you examples of 10 different animals that are cold blooded and learn some interesting facts about them.
Jun 9, 2023 · Animals are classified into two groups based on their energy source: cold-blooded and warm-blooded. The former, also known as ectothermic or poikilothermic animals, lack the ability to regulate their internal temperatures, causing it to fluctuate with their surroundings.
ectotherm, any so-called cold-blooded animal—that is, any animal whose regulation of body temperature depends on external sources, such as sunlight or a heated rock surface. The ectotherms include the fishes, amphibians, reptiles, and invertebrates.
Mar 5, 2024 · Mechanisms. Ectothermic animals regulate their body temperature through behavioral adaptations. For instance, a lizard basks in the sun to warm up or seeks shade to cool down. They also adjust their activities based on the temperature; they are more active when it’s warm and become sluggish in colder conditions. Evolutionary Appearance.
Cold-bloodedness, the state of having a variable body temperature that is usually only slightly higher than the environmental temperature. This state distinguishes fishes, amphibians, reptiles, and invertebrate animals from warm-blooded, or homoiothermic, animals (birds and mammals).
Apr 15, 2023 · Cold-blooded animals, or ectothermic species, rely on their surroundings to regulate body temperature and have a slower metabolism. These animals, including fish, amphibians, insects, and reptiles, adapt to various environments and temperature ranges.
