The best sense of smell
Bears have the best sense of smell. The number of receptors in a bear's nose is seven times higher than in a dog's and about 100 times higher than in a human's. There are known cases of polar bears going after prey from a huge distance. 1)
The largest cats
A liger is a cross between a male lion and a female tiger. Tigers are the largest known cats, reaching over 880 pounds. Interestingly, tigons (a cross between a male tiger and a female lion) do not grow like liger cats. 2)
The longest pregnancy
The elephant is the mammal in which pregnancy lasts the longest. Pregnancy in elephants lasts about 2 years. This is longer than for whales (16 months) and camels (15 months). 3)
The largest eyes
The giant squid has the largest eyes of any animal (except perhaps anecdotal colossal squid), up to 10 inches in diameter. The large eyes allow them to better perceive the sparse light of the deep, including bioluminescent light emitted by living organisms. 4)
The largest wingspan
The wandering albatross has the largest wingspan. The largest albatrosses can reach a wingspan of 11 ft 6 in, while condors and marabouts have a wingspan of about 9 ft 5 in. Albatrosses spend most of their lives in flight, landing only for food or breeding. 5)
