They are warmblooded (meaning they generate their own body heat).

Ice crystals can form in the lungs at temperatures below 32 degrees Fahrenheit (0 degrees Celsius). When breathing in very cold air, the moisture in the lungs can freeze and form ice particles, which can be damaging to the lung tissue.
They don't they are the temperature of the surrounding water, aka cold blooded, with the exception of a very few species.
