and most of them live in the ocean.

Corals are marine invertebrates within the phylum Cnidaria. They typically live in compact colonies of many identical individual polyps. Corals are known for creating coral reefs, which are among the most diverse ecosystems on Earth.
Jellyfish are free-swimming marine animals consisting of a gelatinous umbrella-shaped bell and trailing tentacles. They belong to the phylum Cnidaria, known for their stinging cells called cnidocytes.
Hydra are small, freshwater organisms belonging to the phylum Cnidaria. They are notable for their ability to regenerate and for lacking a fixed shape, as they are capable of moving by looping or somersaulting.
Sponges are invertebrates that belong to the phylum Porifera, not Cnidaria. They are characterized by a porous body structure and do not have the specialized stinging cells (cnidocytes) that cnidarians possess.
Sea anemones are marine animals that belong to the phylum Cnidaria. They are closely related to corals and jellyfish and attach themselves to surfaces in the ocean using a sticky foot called a pedal disc.
