100 Examples of Cold-blooded and Warm-blooded Animals

The animals can be distinguished according to the mechanisms they use to regulate their temperature corporal in:

Studies in thermophysiology determined that there are not only two categories (cold-blooded animals and warm-blooded animals), for which both concepts are vague terms (since not all animals belong entirely to one or another category) and are in disuse in the scientific field. However, both distinctions continue to be used colloquially in some contexts.

Warm-blooded animals

The warm blooded animals They are those that can maintain a constant body temperature regardless of the climatic variations of the environment. They are usually birds or mammals. Most mammals maintain internal body temperature between 34º and 38º. For example: the dog, the lion or the human being.

Warm-blooded animals are also known as endotherms. This type of animal can present some variation in the temperature of its body, but this variation is, generally, minimal.

Types of thermoregulation

Warm-blooded animals can use three processes that allow thermoregulation:

While most warm-blooded animals display all three characteristics of thermoregulation, certain mammals or birds may not have all three conditions, for example, bats or some birds little ones.

Examples of warm-blooded animals

Cold blooded animals

The cold blooded animals They are those that cannot internally regulate their body temperature, so their temperature varies depending on the ambient temperature. This term ("cold-blooded animals") is currently in disuse in the scientific context and instead of animals is used. ectotherms.

Generally, cold-blooded animals are amphibians, insects, fish and reptiles that do not live in environments with very extreme temperature changes. For example: the lizard, the crocodile or the shark.

Types of thermoregulation

Cold-blooded animals can use three processes that allow thermoregulation:

Despite this classification, not all cold-blooded animals have all three characteristics of thermoregulation.
