There are more than a million kinds of bugs on Earth! Some are so tiny you can hardly see them, but some can be very big! • When the bombardier beetle is threatened, it shoots a boiling hot chemical spray from its bum. • A giant weta can weigh as much as three mice. • A Goliath beetle can lift a load that is 850 times heavier than its own weight. That's like a human lifting a jet plane. • Tardigrades are tiny eight-legged creatures that are nearly indestructible. They can live in boiling water, in solid ice, deep in the ocean and in outer space where there is no air.
