Why do some aquatic mammals have dense fur while some have thick blubber instead?
So, are there any disadvantages to having dense fur?
Yes, dense fur can be a disadvantage in warmer waters as it traps heat and can cause an animal to overheat. That's why some aquatic mammals, like dolphins and seals, don't have dense fur and instead rely on blubber to stay warm.
