Variety in Shape and Size
Jellyfish come in many shapes and sizes, from tiny ones only a few centimeters long to the giant lion’s mane jellyfish, which can have tentacles over 100 feet (30 meters) long! Some jellyfish are bioluminescent, meaning they can create their own light to attract prey or confuse predators.
