Do echinodermata lay eggs

Yes, echinoderms, which include sea stars, sea urchins, and sea cucumbers, typically reproduce by laying eggs. Most species engage in external fertilization, where eggs and sperm are released into the water, allowing fertilization to occur outside the body. This reproductive strategy results in the production of large numbers of larvae, which can develop into adults in the ocean. However, some echinoderms may also exhibit different reproductive strategies, including internal fertilization.
