Some animals produce a bad smell to determine their territory, repel scavengers from their food, or when they feel danger in front of predators, to keep them away from their target and to be safe.
Centipedes are one of those creatures that repel enemies by emitting hydrogen cyanide poisonous gas when they feel threatened. One centipede can kill 6 mice and 100 thousand centipedes can kill a human.
A tropical and smelly bird named Hoatzin lives in the Amazon forests and the Orinoco region in South America, which feeds on tree leaves. The different digestive system of this bird causes that the combination of the smell of plants and bacteria in the front part of the intestine of this bird, which is used to ferment its nutrition, produces a smelly gas similar to animal manure.
There is also a species of weasel called the Eurasian otter that defends itself when faced with predators by emitting a smelly gas that can be smelled up to half a mile away.
Another smelly creature is the small anteater, which, although its smell does not reach more than 50 meters, the intensity of its smell is 4 to 7 times that of the Eurasian otter, and it has been introduced as one of the smelliest animals.
The Tasmanian devil is one of the animals found only on the island of Tasmania, Australia, and produces a bad smell when stressed to protect its environment. This animal does not smell bad until it feels threatened.
A woolly and horned mammal called the musk ox, which lives in the Arctic, during the mating season to determine its territory, produces a bad smell by dipping its hair in its urine so that the creature does not approach that place.
Skunks are a type of weasel that repels enemies by producing a bad smell due to their low speed when fleeing from danger. This smell is a mixture of sulfuric which is found in the body of skunks as much as 15 cc and it is sprayed up to a radius of three meters to repel danger and its smell can be smelled for miles. Skunks need a week to rebuild their weapon after each use.
