Why do some aquatic mammals have dense fur while some have thick blubber instead?
I was just curious about something. Why do some aquatic mammals have dense fur while others have thick blubber?
That's an interesting question. Dense fur helps to insulate aquatic mammals like sea otters and polar bears in cold waters. On the other hand, thick blubber helps animals like whales and walruses stay warm and store energy in cold environments.
