Is a fish cold blooded or warm blooded?

Fish are cold-blooded, also known as ectothermic. This means they rely on their external environment to regulate their body temperature.

Here's why:

* Lack of Internal Temperature Regulation: Unlike warm-blooded animals (endothermic), fish don't have the ability to generate their own body heat through internal processes like metabolism.

* Temperature Fluctuation: Their body temperature fluctuates with the surrounding water temperature. If the water gets colder, so does the fish.

* Behavioral Adaptations: Fish use various behaviors to adjust their body temperature, such as seeking out warmer or colder water, basking in the sun, or swimming to different depths.
