Usually, animals use their ability to spit acid as a defense mechanism. They do this to deter predators or to blind them so they can escape.
There are only a few animals in the world that can spit acid. Here are some of them:
Spitting cobras are found in Africa and Asia. They can spit a stream of venom up to 10 feet away. The venom can cause blindness, respiratory problems, and even death.
Some species of bombardier beetles can spray a hot, boiling chemical mixture from their abdomens. The mixture can reach temperatures of up to 212 degrees Fahrenheit and can cause severe burns.
The horned lizard also known as the horny toad, can squirt a stream of blood from its eyes. The blood is not actually acidic, but it can still cause irritation and blindness to predators.
The leafhopper is a small insect that can spray a sticky substance from its mouth. The substance is not actually acidic, but it can coat the predator’s eyes and make it difficult for them to see
