Sea worms mate in the following way: at mating time, males and females swarm together. Suddenly the females turn on the males and bite their tails off. The tails contain the males’ testes and sperm. When they are swallowed and acted upon by the females’ digestive juices, they fertilize her eggs.

Cheetahs are carnivores, and feed mostly on smaller antelope like springbok, steenbok, Thomson’s gazelle, and duiker. They usually chase down their prey and then bite its throat, killing it by cutting off its air supply (suffocation).
