Sharks have the most amazing sense of smell. They breathe entirely with their gills, so their nose is used only for smell. They’re able to sniff out prey with just a few drops of blood in a pool of water the size of an Olympic swimming pool!
Researchers tracked Polar Bears for 64 kilometres as the bears walked in a straight line all the way to a group of seals. They sniffed them out from that great distance away!
Snakes might have nostrils but they don’t use them for smelling. They smell with their tongues! They will stick their tongue out and flick it around to sniff out their surroundings.
While flying through the air, an albatross will change direction quickly if it smells its prey.
Rabbits actually use their noses to sniff out food underground. Have you ever seen a rabbit twitching its nose up and down? It’s smelling!
Foxes mark their territory with scent to let others know which areas are theirs. It smells a bit like cat pee. Eww.
