Human's Temperature
For a typical adult human, the body temperature can be anywhere from 97 F (36.1°C) to 99 F (37.2°C). Babies and children have a little higher range: 97.9 (36.6°C) F to 100.4 F (38°C).
Animal's Temperature
Hummingbird has the highest body temperature, i.e., 107°(41.7°C). Elephants and whales belong to mammals that have body temperature ranging from 97° (36.1°C) to 103° (39.4°C). Monkeys are closely related to human body temperatures going from 98.6° to 103.1°. Snake can't adjust his temperature.
Earth Temperature
The average temperature on the earth's surface is about 16°C, but in the earth's core, the temperature is 350 times this temperature. Scientists estimate that the temperature is as high as 5600~6000°C, which is slightly higher than the sun's surface (5600°C).
Bear's Temperature during Hibernation
In the hibernation of bears, their body temperature did not drop much, but it was a little lower than usual. Breathing decreased from six to ten breaths per minute to about once (-6x), and heart rate dropped from about 50 beats per minute to about 15 beats per minute (-1/3). Its metabolism level has also declined to one-fourth of its usual activity. They have not eaten or drank during these few months but just slept and occasionally turned over to adjust their sleeping posture.
