Typical core body temperature ranges for different animal groups:
1. Mammals: Most mammals are considered endothermic or "warm-blooded," meaning their bodies maintain a relatively constant core temperature regardless of external conditions. The typical mammal's core temperature ranges between 35.5°C to 39.5°C (95.9°F to 103.1°F). Humans have a core body temperature of around 37°C (98.6°F).
2. Birds: Like mammals, birds are endothermic and maintain a high core body temperature to support their active metabolism and flight abilities. Bird core temperatures typically range from 40°C to 44°C (104°F to 111.2°F).
3. Reptiles: Reptiles are ectothermic or "cold-blooded," meaning their body temperature primarily depends on the environment. Their core temperature fluctuates based on the ambient temperature, but optimal core temperatures for reptiles vary depending on the species. It usually lies between 25°C to 35°C (77°F to 95°F).
4. Amphibians: Amphibians, like reptiles, are ectothermic and have variable body temperatures. They often rely on external sources like sunlight to regulate their core temperature. The optimal core temperature range for amphibians can be between 20°C to 35°C (68°F to 95°F).
5. Fish: Fish are ectothermic and have body temperatures determined by the temperature of the water they inhabit. The core body temperature of fish typically varies along with the water temperature and may range between 5°C to 35°C (41°F to 95°F).
6. Insects: Insects are also ectothermic, and their core body temperature primarily depends on their surroundings. Insect body temperatures are often within the same range as their environments or slightly higher, usually ranging between 10°C to 45°C (50°F to 113°F).
It's important to note that these temperature ranges are general guidelines, and specific animal species may have specific temperature preferences or adaptations.
