We all know that our planet is unique – since it supports life. We also know that there are different flora and fauna and some of these have unique features. For instance, the African elephant is the largest land mammal, and the blue whale is the largest mammal on Earth!
But did you know that there is a small nocturnal mammal native to the rainforests of Central and South America that are known for its unique behaviour of self-destruction? This is thought to be a defense mechanism against predators.
Yes, you read that right. The Barbosa (Babirusa) will release a foul-smelling liquid from its glands when threatened. This liquid is so strong that causes the predators to vomit and flee. However, the Babirusa will often consume the liquid itself, which can lead to death.
Why does this happen?
Scientists are not entirely sure of the reason why Babirusa engages in this behaviour. Some believe that it is a way to avoid being eaten, while others believe that it is a way to communicate with other Barbosas. Whatever the reason, the animal’s self-destructive behaviour is truly unique in the animal kingdom.
Here’s what happens
When threatened, the Babirusa will release a foul-smelling liquid from its glands. This liquid is made up of a mixture of chemicals, including hydrogen sulfide, ammonia, and sulfur dioxide. Scientists believe that the self-destructive behaviour is a defense mechanism. By consuming the liquid, the Barbosa is making itself less attractive to predators.
This self-destructive behaviour has been documented by scientists for many years. In one study, scientists observed a group of Barbosas being attacked by a group of snakes. When the snakes cornered the Barbosas, the Barbosas released their foul-smelling liquid and consumed it themselves. All of the Barbosas died as a result.
Another study found that Barbosas are more likely to engage in self-destructive behaviour when they are stressed. In the study, scientists exposed Babirusas to a variety of stressors like loud noises and bright lights. Those exposed to the stressors were more likely to release their foul-smelling liquid and consume it themselves.
Food for thought
1. The self-destruction may be a way to avoid being captured and eaten by predators.
2. The foul-smelling liquid may be toxic to parasites, and by consuming it, the Babirusa is killing off any parasites that may be living on its body.
3. The foul-smelling liquid may serve as a warning signal to other animals that danger is near, or it may simply be a way to mark territory.
4. It is the only known animal in the world that engages in self-destruction as a defense mechanism.
5. Self-destructive behaviour is thought to be a learnt behaviour. Young Babirusas are not born with this behavior, but they learn it from their parents.
6. They are very social animals. They live in groups of up to 20 individuals.
7. They are omnivores. They eat a variety of plants and insects.
