What is the function of the medusa stage?

The medusa stage is the free-swimming phase in the life cycle of cnidarians, such as jellyfish. Its primary function is reproduction; medusae produce gametes that facilitate sexual reproduction, leading to the formation of zygotes. Additionally, the medusa stage allows for dispersal and movement through the water, enabling the organism to colonize new areas and find food. Overall, it plays a crucial role in the lifecycle and ecological success of cnidarians.
