Answer 2

Answer: The sperm whale

Explanation:

• Bigger brains don't necessarily make a mammal smarter. But as mammals evolved, many groups, from primates to carnivores, showed independent increases in brain size.
• The fact that unusually large brains appear again and again in mammalian evolution suggests that larger brains must confer some significant advantages.
• The night tarsus is only 3.5 inches tall but has the largest eyes relative to the body size of any mammal. The eyes are the same volume as the animal's entire brain to catch the light on dark nights.
• This fact is not so hard to believe considering that the sperm whale (or cachalot) is the largest toothed whale, not to mention the largest toothed predator.
• Males are usually larger than females with an average length of a whopping 52 feet

Hence the sperm whale has the heaviest brain which weighs from 7 to 9 kilograms.
