An ectotherm (from the Greek ἐκτός (ektós) "outside" and θερμός (thermós) "heat"), more commonly referred to as a "cold-blooded animal", [1] is an animal in which internal physiological sources of heat, such as blood, 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.
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.
Aug 3, 2023 · Cold-blooded animals include reptiles, fishes, amphibians, insects, and other invertebrates. These animals are also called poikilothermic animals. Cold-blooded animals usually demonstrate any three of the thermoregulation mechanisms; Poikilothermy, Ectothermy, or Heterothermy.
Mar 5, 2024 · Let’s explore the fascinating differences between ectothermic (cold-blooded) and endothermic (warm-blooded) animals, shedding light on their definitions, evolutionary history, mechanisms, and the pros and cons of each thermal strategy.
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).
Dec 23, 2019 · Cold-blooded Animals. Most reptiles, amphibians, fish, and insects are unable to maintain their core body temperatures from within. They are, therefore, dependent on the temperature from their surroundings. Such organisms are therefore known as ectotherms (ecto meaning outside + therm meaning heat).
Oct 19, 2023 · An ectotherm, commonly referred to as a cold-blooded animal, relies on external heat sources to control its body temperature, which can fluctuate widely based on the animal's surroundings. This is different from endotherms, who regulate their internal temperature based on heat produced within the body.
