Which classification describes animals like salamanders?

The classification that describes animals like salamanders is "ectotherms." Ectothermic animals, often referred to as cold-blooded animals, rely on environmental heat sources to regulate their body temperature. This means their internal temperature varies with the external environment, which is typical of amphibians like salamanders. They often bask in the sun to warm up or seek shade or water to cool down.

In contrast, endotherms, or warm-blooded animals, maintain a constant internal body temperature regardless of external conditions, which is not applicable to salamanders. The terms oviparous and viviparous describe reproductive strategies. Oviparous species lay eggs that develop outside the mother’s body, while viviparous species give live birth. Although some salamanders are oviparous, the most relevant classification for their physiological temperature regulation is that they are ectotherms.
