Definition
Meaning and Definition
An animal with a body temperature that remains relatively constant and largely independent of the environmental temperature; a warm-blooded animal.
A living organism, especially a mammal or bird, capable of maintaining a stable internal temperature through metabolic processes, regardless of external conditions. In broader scientific discourse, the term can be applied to any endotherm.
Dialectal Variation
British vs American Usage
Differences
No significant difference in meaning or usage. The term is equally rare and technical in both varieties. The spelling 'homoeotherm' (with 'oe' ligature) is a less common variant, but the '-oi-' spelling is standard.
Connotations
Purely technical, clinical, and academic. No colloquial or figurative use.
Frequency
Extremely rare in general usage. Used almost exclusively in advanced academic textbooks and research papers in biology. 'Warm-blooded' or 'endotherm' are far more common even in scientific contexts.

Examples of “homoiotherm” in a Sentence
adjective
British English
- The homoiothermic condition requires a high metabolic rate.
- They studied homoiothermic responses in juvenile birds.
American English
- Homoiothermic regulation is energetically costly.
- The fossil evidence suggests a homoiothermic physiology.
Usage
Meaning in Context
Academic
Essential in advanced biology and physiology texts discussing thermoregulation and metabolic adaptation. E.g., 'The paper contrasts the energy budgets of homoiotherms and poikilotherms.'
Everyday
Virtually never used. 'Warm-blooded' is the universal term.
Technical
The primary domain of use. Precise term in zoology, comparative physiology, and paleontology.
Watch out
Common Mistakes When Using “homoiotherm”
- Misspelling: 'homeotherm', 'homootherm'. Incorrect pronunciation placing stress on the first syllable. Using it in non-scientific contexts where it sounds jarringly technical.
FAQ
Frequently Asked Questions
Yes, in essence. 'Homoiotherm' is the precise, formal scientific term, while 'warm-blooded' is the common, non-technical equivalent.
They are largely synonymous. 'Homoiotherm' emphasises the *constancy* of temperature (from Greek 'homoios' = similar). 'Endotherm' emphasises that the heat is generated *internally* (from Greek 'endon' = within). In modern biology, 'endotherm' is slightly more prevalent.
Virtually all, yes. Some, like hibernating animals or naked mole-rats, can allow their temperature to vary under specific conditions, but they retain the physiological capacity for homoiothermy.
It is a highly specialized taxonomic/physiological term. In most discussions, even academic ones, 'endotherm' or the phrase 'warm-blooded animal' is sufficient and more readily understood.
An animal with a body temperature that remains relatively constant and largely independent of the environmental temperature.
Homoiotherm is usually highly technical/scientific in register.
Homoiotherm: in British English it is pronounced /hɒˈmɔɪ.ə.θɜːm/, and in American English it is pronounced /hoʊˈmɔɪ.oʊ.θɜːrm/. Tap the audio buttons above to hear it.

Mnemonic
Think: 'HOME-O-THERM'. A homoiotherm keeps its internal temperature at a steady, 'homey' level, like a well-regulated home thermostat.
