Question

How are mammals able to stay in cold water for a long time?

Answer 1

Answer:

Hey mate here is your answer......

Whales, dolphins, seals and other marine mammals can generate their own heat and maintain a stable body temperature despite fluctuating environmental conditions. Like people, they are endothermic homeotherms—or more colloquially, "warm-blooded."

But these animals take thermoregulation to an extreme, enduring water temperatures as low as –2 degrees Celsius (28.4 degrees Fahrenheit) and air temperatures reaching –40 degrees C (–40 degrees F).
