So how do they do it?Although they have no central brain, the jellyfish do have a nervous system(神经系统). It's made of four main parts that look like hanging strings(绳子).Each part has about 1,000 neurons(神经元) and six“simple” eyes. This lets them see and avoid things and...

Jellyfish are carnivores -- they eat other animals. Smaller jellyfish eat algae and other tiny plankton called zooplankton. Larger jellyfish eat crustaceans and other bigger aquatic animals. They don't seek out people to attack -- their nervous system is too simple to do that. Their sting is...
