"1117225029"^^ . . "Les animaux po\u00EFkilothermes (dits \u00E0 \u00AB sang froid \u00BB ou encore p\u0153cilotherme) sont des animaux ayant une temp\u00E9rature corporelle qui varie avec celle de leur milieu.Par cette caract\u00E9ristique, ils diff\u00E8rent et s'opposent aux hom\u00E9othermes qui ont une temp\u00E9rature interne relativement stable.Ils ne sont pas \u00E0 confondre avec les h\u00E9t\u00E9rothermes qui sont des hom\u00E9othermes dont la temp\u00E9rature corporelle habituellement stable, varie dans certains cas (les animaux qui hibernent, les nourrissons dont la temp\u00E9rature corporelle n'est pas encore stable, etc.). Ils sont qualifi\u00E9s \u00E0 tort d'animaux \u00AB \u00E0 sang froid \u00BB car leur temp\u00E9rature corporelle varie. La plupart des organismes po\u00EFkilothermes (qui ne contr\u00F4lent pas leur temp\u00E9rature corporelle) sont \u00E9galement ectothermes (c'est-\u00E0-dire que leur chaleur corporelle provient de l'ext\u00E9rieur). Il existe toutefois des cas particuliers et il est n\u00E9cessaire de rappeler que po\u00EFkilotherme et ectotherme ne sont pas synonymes. Par exemple, certains poissons des mers sont ectothermes (incapable d'utiliser leur \u00E9nergie cellulaire pour augmenter leur temp\u00E9rature corporelle) mais ne sont pas po\u00EFkilothermes car la temp\u00E9rature de l'eau dans laquelle ils se trouvent ne varie jamais. Cette non-ma\u00EEtrise de leur temp\u00E9rature interne les emp\u00EAche d'avoir une activit\u00E9 \u00AB normale \u00BB lors des p\u00E9riodes froides, mais c'est une caract\u00E9ristique beaucoup plus \u00E9conome en \u00E9nergie que les hom\u00E9othermes. Les deux types ont surv\u00E9cu car ils sont caract\u00E9ristiques de modes de vie diff\u00E9rents.Comme les insectes, les poissons et les reptiles, les animaux \u00E0 sang froid ne peuvent pas contr\u00F4ler leur temp\u00E9rature ambiante. Certaines doivent se r\u00E9chauffer une fois le jour venu, afin de reprendre leur activit\u00E9 normale."@fr . . . . . . . . . "Zwierz\u0119 zmiennocieplne"@pl . . . . . . .

Die meisten Tiere sind wechselwarm, beispielsweise alle Fische, Amphibien, Reptilien, Insekten und alle anderen wirbellosen Tiere. Gleichwarm sind dagegen alle V\u00F6gel und S\u00E4ugetiere (zu Einschr\u00E4nkungen dazu vergleiche aber Torpor). Grunds\u00E4tzlich entspricht die K\u00F6rpertemperatur wechselwarmer Tiere der Umgebungstemperatur. Aufgrund der RGT-Regel sind sie bei niedrigen Temperaturen weniger aktiv. Allerdings beeinflussen einige wechselwarme Tiere durch ihr Verhalten die K\u00F6rpertemperatur. So suchen viele Reptilien gezielt sonnige oder schattige Pl\u00E4tze auf, einige Reptilien nutzen sogar die W\u00E4rmebildung gleichwarmer Arten (Kleptothermie). Haie dagegen steigern ihre K\u00F6rpertemperatur durch intensive Bewegung.

While the term in principle can apply to all organisms, it is generally only applied to animals, and mostly to vertebrates. Usually the fluctuations are consequence of variation in the ambient environmental temperature. Many terrestrial ectotherms are poikilothermic. However some ectotherms remain in temperature-constant environments to the point that they are actually able to maintain a constant internal temperature (i.e. are homeothermic).It is this distinction that often makes the term \"poikilotherm\" more useful than the vernacular \"cold-blooded\", which is sometimes used to refer to ectotherms more generally. Poikilothermic animals include types of vertebrate animals, specifically some fish, amphibians, and reptiles, as well as many invertebrate animals. The naked mole-rat and sloth are some of the rare mammals which are poikilothermic."@en . . . "Les animaux po\u00EFkilothermes (dits \u00E0 \u00AB sang froid \u00BB ou encore p\u0153cilotherme) sont des animaux ayant une temp\u00E9rature corporelle qui varie avec celle de leur milieu.Par cette caract\u00E9ristique, ils diff\u00E8rent et s'opposent aux hom\u00E9othermes qui ont une temp\u00E9rature interne relativement stable.Ils ne sont pas \u00E0 confondre avec les h\u00E9t\u00E9rothermes qui sont des hom\u00E9othermes dont la temp\u00E9rature corporelle habituellement stable, varie dans certains cas (les animaux qui hibernent, les nourrissons dont la temp\u00E9rature corporelle n'est pas encore stable, etc.). Ils sont qualifi\u00E9s \u00E0 tort d'animaux \u00AB \u00E0 sang froid \u00BB car leur temp\u00E9rature corporelle varie."@fr . . . "9495"^^ . . . . . . . . . . "Wechselwarmes Tier"@de . . .
