Poikilothermic

Relating to organisms that cannot regulate their body temperature internally, thus their body temperature varies with the environmental temperature. poikilothermic organisms, often referred to as 'cold-blooded' animals, include many reptiles, amphibians, and fish. They depend on external heat sources to maintain the necessary metabolic rates required for survival.

Poikilothermic meaning with examples

• The lizard is a classic example of a poikilothermic animal, relying on the warm sun to raise its body temperature and facilitate digestion, which is crucial for its survival in the wild.
• During the winter, poikilothermic species like frogs and turtles enter a state of hibernation, slowing their metabolism significantly to conserve energy while the surrounding temperatures drop.
• Aquatic ecosystems show a diverse range of poikilothermic organisms, where species like jellyfish and many types of fish can adapt their behavior according to the water's temperature.
• Poikilothermic animals often demonstrate fascinating behaviors, such as basking in the sun, which helps them reach optimal body temperatures necessary for reproductive activities, feeding, and locomotion.
• Understanding the poikilothermic nature of certain species can help researchers assess how climate change might impact their populations, as rising temperatures can influence their habitat and breeding cycles.
