What is the most common type of reproduction in cnidarians?

The most common type of reproduction in cnidarians is asexual reproduction, primarily through budding. In this process, new individuals grow from an outgrowth or bud on the parent organism, eventually detaching to become independent. Cnidarians can also reproduce sexually, typically by releasing eggs and sperm into the water, leading to fertilization and the development of larvae. However, asexual reproduction is often more prevalent, especially in sessile forms like corals and hydras.
