Six Animals With Best Sense of Smell

in Education

Animals have different ways to use their noses in detailed purposes. Some animals depend on noses to catch prey and others consider noses as one useful way to fight for territory. However, there are several species whose noses become the most prominent and attention-grabbling body parts with the best sense of smell.

 

The Bear

Though the brain size of a bear is one third of ours, its nose is much big and the part devoted to smell is five times larger. The inside surfaces of bears’ nostrils are enlarged with folds to make room for thousands of smell receptors.

The Shark

A shark can detect the tiniest blood drop from more than a mile away because two-third of its brain is dedicated to smell, even uninjured fish may face with many dangerous cases from the shark’s surveillance.

The Rat

Like dogs, rats can be trained to use their best sense of smell in stereo with each nostril working independently to detect land mines and the scent of explosives like TNT. At present, giant African pouched rats are able to complete the dangerous mission well.

The Pinocchio Frog

The Pinocchio Frog, a bizarre new species of tree frog discovered in the Foja mountains rainforest on the Indonesian island of New Guinea, has an unusual spiky nose. Interestingly, its nose points upwards when the male calls but deflates and points downwards when he is less active.

 

The frog was first found sitting on a back pack in the researchers’ campsite

The Albatross

Most birds often have a poor sense of smell but the albatross is an exceptional. It spends much time hovering above the ocean to look for food and its extra-large nose on top of the beak will help detect food floating on the sea, even in dark sky.

The Star-Nosed Mole

The star-nosed mole, a small and weird-looking mammal, is found in the wetlands of eastern North America ranging from Canada to Georgia. Because this mole lives in almost complete darkness like underground tunnels, it is virtually blind. Therefore, the mammal mainly depends on its remarkable-looking star-shaped nose to locate food.
