Budding

In budding, new offspring buds and grows from the main body of the animal. The "new" organism eventually detaches itself and lives on its own.

Other animals that undergo budding are jellyfish, sponge, and corals. Corals are tiny sea animals that produce outer skeletons that resemble shells. Unlike hydras, a newly produced coral does not detach itself from the parent and this leads to the formation of groups of corals on the ocean floor.
