Jellyfish Light Ocean Crafts

Here are some fun science facts for kids about jellyfish. These ocean squirmers are made up of 90% water and are nearly see through. Some jellyfish species are invisible to the human eye because they are so transparent. You might have guessed that since these jellies are see through there isn’t much going on inside. They have no brain, blood, or nervous system. However, they do come in all kinds of colors and blends. In fact, some species of jellyfish glow in the dark, adding to their vibrant color. Jellyfish snack on tiny fish and plants in the ocean, but apparently, they’ll enjoy a sweet peanut butter treat from time to time in captivity. Jellyfish have are one of the oldest ocean species on earth. They’re over 500 million years old! If you ever visit the aquarium to visit our little jelly friends, you may notice that their tanks are usually circular. This is to prevent them from getting stuck in the corners of the tank. No worries, though. These little guys love trekking across the entire world, living in every single ocean on the planet.
