Answer 2

Whales have blubber while, fish do not have blubber

• Whales are warm-blooded mammals.
• Warm-blooded animals have a mechanism for internal temperature regulation, that is their internal temperature remains constant regardless of the temperature of the environment outside.
• Thus, in order to maintain a constant internal temperature whales have a layer of blubber (fat) present inside them.
• Fish are cold-blooded animals, that is they do not have any means for internal temperature regulation and their internal temperature varies according to the environment.
• Thus, fish do not need blubber and differ from whales in having (Option A) Blubber.
