Homoiothermic Meaning: Definition, Examples, and Translations
🐦
homoiothermic
[həˌmɔɪoʊˈθɜrmɪk ]
Definition
biological classification
Homoiothermic organisms, also known as warm-blooded animals, maintain a constant internal body temperature regardless of external environmental conditions. This thermoregulation allows them to inhabit diverse climates and engage in metabolic activities with greater efficiency.
Synonyms
endothermic, warm-blooded.
Examples of usage
- Birds are homoiothermic animals that can regulate their body temperature even in cold weather.
- Mammals, including humans, are classified as homoiothermic due to their ability to maintain a stable internal temperature.
- Many homoiothermic species exhibit behavioral adaptations to conserve heat in winter.

Interesting Facts
Biology
- Mammals and birds are examples of homoiothermic animals, requiring energy to maintain body heat.
- This ability allows them to live in diverse environments, from hot deserts to icy poles.
Evolution
- The development of homoiothermy is believed to be a key factor in the survival of species during fluctuating climates.
- Warm-blooded animals often have higher metabolic rates, giving them a competitive advantage in hunting and foraging.
Comparative Physiology
- In contrast to homoiothermic animals, poikilothermic animals (like reptiles) have varying body temperatures that change with their environment.
- Homoiothermic species can remain active in cooler temperatures, unlike their cold-blooded counterparts.
Animal Behavior
- These animals often exhibit behaviors such as basking in the sun or seeking shade to help regulate their temperatures.
- Nesting and burrowing behaviors are critical for maintaining warmth during colder seasons.
Origin of 'homoiothermic'
Main points about word origin
- The term originates from the Greek words 'homoios' meaning 'similar' or 'same' and 'thermos' meaning 'heat'.
- It was first used in scientific literature in the early 19th century to describe warm-blooded animals.
The term 'homoiothermic' is derived from the Greek roots: 'homoios', meaning 'similar' or 'alike', and 'thermos', meaning 'heat'. It first appeared in scientific literature in the late 19th century as researchers began to study the thermoregulation mechanisms in animals. The concept reflects biological adaptations that allow certain species to thrive in various habitats. This adaptation is particularly evident in mammals and birds, which evolved strategies such as insulation, metabolic adjustments, and behavioral changes to maintain their body temperature, especially in fluctuating environmental conditions. Over time, the understanding of homoiothermic organisms has expanded, contributing significantly to the field of ecology and evolutionary biology.
