How nature de
MOST animals use defence mechanisms that are well known, including playing dead, using camouflage to blend into the background or having eyes on the side of the head to see predators more easily.
Some animals have evolved unique defences to avoid becoming someone else’s dinner. Here are a few of them.
Skipper caterpillar: This wily invertebrate can shoot poop pellets five feet through the air! This is the equivalent to a 1.8m man throwing a ball 73m. Scientists think skipper caterpillars do this when threatened because wasps are attracted to the smell of their droppings. This sends the wasps on a wild goose chase giving the caterpillar time to get away.
Horned lizard: There are 15 species of horned lizards in North America. Four of them have the ability to squirt blood out of their eyes when threatened. During an attack, the lizard is able to reduce the flow of blood to the rest of the body. This increases the pressure in tiny blood vessels near the eye, causing them to burst and spewing a stream of blood. In addition to confusing a predator, the blood tastes awful.
Malaysian ant: Like other ants, a Malaysian ant colony consists of many players: the queen, workers, soldiers and drones (the queen’s mates). If a colony is threatened, it is a soldier’s job to defend its com-
GLANDS: When they sense an attacker, they contract their abs, and release their glandular contents from the head.
