Comb jellies are invertebrate sea creatures that bear visual resemblance to Jellyfish, but have no actual relationship to them in zoology. There are about 150 species of comb jellies that live in the ocean, ranging from shallow to very deep waters.
Like jellyfish, comb jellies have transparent bodies, and may have thin tentacle appendages on their bodies, though comb jelly tentacles do not sting.
The most notable feature about the comb jelly is the 8 rows of cilia that run along each jelly's body like comb teeth. These fins are usually used to swim in the water, and due to their iridescence in many species, can refract in dazzling rainbows when in the light. These light shows are used to attract and mesmerize their prey.
