A:

Quick Answer

Some examples of cold blooded animals are snakes, fish, crocodiles, lizards, frogs and turtles. As a general rule, most amphibians, reptiles and fish are cold blooded. Cold blooded animals cannot maintain their body temperature by themselves. Their body temperature depends on their environment.

Full Answer

Cold blooded animals maintain their body temperature by seeking environments that match the temperature they require. The term "cold blooded" is inaccurate; these animals are now called ectotherms, which means they regulate their body heat by absorbing or releasing heat into their surroundings. They do this using a variety of bodily mechanisms. Fish can sense the water temperature around them and swim to a depth that suits their body temperature. Lizards bask in the sun to increase their body temperature and move in to the shade when they get too hot. Animals in desert regions need to avoid overheating in the hot sun. Often times shade may not be available due to lack of vegetation, and in such cases, snakes and other cold blooded animals burrow in the sand where the temperature is lower than the surface temperature. Insects need to warm their flight muscles before taking off and do so by vibrating them while staying in the same place. These mechanisms that maintain body temperature are occasionally used by warm blooded animals as well, especially when surviving in environments with extreme variances in temperature.
