1. Varying in temperature according to the temperature of the surrounding medium; denoting the so-called cold-blooded animals, such as the reptiles and amphibians, and the plants.
2. Capable of existence and growth in media of varying temperatures. Compare: heterothermic, homeothermic.
3. Causing a disruption of normal hypothalamic thermoregulatory function, as seen with drugs such as phenothiazines.

Poikilothermic (cold-blooded) animals are clearly dependent on the environmental temperature, as their metabolic processes are directly influenced by the external temperature: If it is cold, these processes are slower and the successive phases of the annual cycle are retarded; when it is hot, they speed up.
Because mollusks are poikilothermic organisms, the temperature of the water must be taken into account when evaluating oxygen consumption.
Respiration rates were adjusted for temperature, so this seasonal effect on community respiration rates was not a direct effect of temperature on poikilothermic metabolic rates.
We all live in a world run by cryptorchid, poikilothermic decerebrates, but if you read this column regularly you need never feel alone again.
Fish are poikilothermic animals and their physiology is fundamentally affected by environmental temperatures (Cho et al.
Typically, temperature elevation accelerates poikilothermic growth until a species-specific thermal maximum is attained, beyond which growth and/or survival is depressed (Kinne 1970, Hochachka & Somero 2002).
Fish species are poikilothermic and their feed intake, growth and metabolic responses are affected by surrounding temperature (Peres and Oliva-Teles, 1999).
Ants are poikilothermic, thus their foraging activity depends on different abiotic factors like relative humidity and soil temperature (Traniello 1989; Valenzuela-Gonzalez et al.
1998), and small variations in temperature may have dramatic effects on the developmental and transmission rates of helminth parasites, as well as on the distributions and developmental rates of their poikilothermic intermediate hosts.
As expected for poikilothermic animals, activity between cohorts differed, most likely reflecting seasonal patterns.
