What body temperature Do animals drop?
Cold-blooded animals do not maintain a constant body temperature. They get their heat from the outside environment, so their body temperature fluctuates, based on external temperatures. If it is 50 °F outside, their body temperature will eventually drop to 50 °F, as well.
How do animals regulate their body temperature?
Many animals regulate their body temperature through behavior, such as seeking sun or shade or huddling together for warmth. Some animals use body insulation and evaporative mechanisms, such as sweating and panting, in body temperature regulation.
What type of animal will show a decrease in body temperature and metabolic rate when in cold temperatures?
Torpor
Torpor is a state of decreased physiological activity in an animal, usually by a reduced body temperature and metabolic rate. Torpor enables animals to survive periods of reduced food availability….Notes.

Does higher body temperature mean higher metabolism?
Effect of Temperature on Metabolic Rate. It has been known since early in the 20th century that a rise in temperature is associated with an increase in metabolic rate. Each degree C rise in temperature is associated with a 10–13% increment in oxygen consumption (18).
How does the temperature of an animal work?
The body can only work properly at a certain temperature. The animal body maintains itself at a constant temperature, within a small range, in order for the systems to work properly. This normal body temperature is different in different types of animals. There are a number of ways by which animals control the temperature of the body:
Why are ectotherms referred to as cold blooded animals?
They are colloquially referred to as cold-blooded despite the fact that body temperatures often stay within the same temperature ranges as warm-blooded animals. Ectotherms are the opposite of endotherms when it comes to regulating internal temperatures.
Is the body temperature of all mammals thermoregulated?
Contrary to the popular belief, not all mammals are warm-blooded and some can drop their body temperature below zero. Endothermy, homeothermy, and tachymetabolism are the three categories of thermoregulation, and most warm-blooded animals fall into all of these three categories.
Why do warm blooded animals lose more heat than they gain?
This is because in warm-blooded animals, the heat they lose is proportional to the surface area of their bodies, while the heat they produce is proportional to their mass. This means that larger warm-blooded animals can generate more heat than they lose and they can keep their body temperatures stable more easily.

Why does an animal’s body temperature decrease when it is under water?
They float on the surface of the ocean to absorb heat and then, after submerging again, stay homeothermic for periods of time because of their sheer size. During long periods of time underwater their body temperature may decrease, depending on the temperature of the surrounding water.

How does the body temperature change during hibernation?
The physiological changes of hibernation (9) are quite severe and designed to enable the animal to save energy and survive without eating for long periods of time. During hibernation, an animal’s metabolic rate slows to as low as 2% (10) of normal levels. Their body temperatures can drop by as much as -2.9 degrees Celsius.
