Question

a seal is a mammal. How can it survive in the cold polar seas when a human would die in a few minutes?

Answer 1

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).
