Jellyfish are invertebrate animals belonging to the group of cnidarians. They are known for their bell-shaped body and stinging tentacles.
Jellyfish live in aquatic environments, primarily in the ocean. They have a gelatinous and transparent structure that allows them to float in the water.
Their tentacles contain specialized cells called cnidocytes, which they use to capture prey and defend themselves. Jellyfish can vary in size and color, and some species are bioluminescent.
Although they are usually harmless to humans, jellyfish stings can cause discomfort and allergic reactions.
