What animal can smell better than a dog?

Whitetail Deer have up to 297 million olfactory receptors compared to humans with just 5 million and dogs with 220 million. Whitetail deer's sense of smell is nearly 1/3 greater than that of a canine or dog. A deer can detect the odor of approaching danger several hundred yards away.

Why do animals have better smell?

Do possums have a good sense of smell?

Opossums have a keen sense of touch. Their sense of smell is exceptional–they have 1,188 genes devoted to smell. (By comparison, humans have 396 olfactory genes.) Their eyesight is poor, however, and their senses of hearing and taste are rather weak, too.

What animal has the best sense of touch?

Strongest sense of touch: manatee

Manatees, though, have what is referred to as the ability to "touch at a distance," meaning that they can feel things without even touching them, even if those things are really far away.

Do goats have a good sense of smell?

Goats' great sense of smell also plays an important role in feeding, avoiding predators, and social activities. The damp skin on their noses and inside their nostrils has many more sensors than humans have. ... They also like to sniff other animals and humans on introduction.

What animal has 8 hearts?

The animal with eight hearts is Barosaurus.

Having eight hearts means that a lot of pressure is required for blood circulation in the body.

Which animal has the biggest balls?

North Atlantic right whales have the largest testicles in the animal kingdom. They can exceed 900 kg, which corresponds to about 2% of the animal's total weight. Harbour porpoises have nothing to be ashamed of either: during the mating season, the testicles of males swell to represent 5% of their body weight.

Which animal has the biggest brain?

The sperm whale has the biggest brain of any animal species, weighing up to 20 pounds (7 to 9 kilograms). Larger brains don't necessarily make a smarter mammal.
