Echinoderms are a category of sea invertebrates; there are 5 groups of echinoderms, Asteroidea, Crinoidea, Echinoidea, Holothuroidea and Ophiuroidea. A sea cucumber is a holothuroidea; their lengthy body surrounded by leathery skin identifies holothuroideas. A sea lily is a crinoidea; crinoidea feed off the seabed with a mouth at the top of their body.
Yes, sea urchins are herbivores because they mainly feed on algae.
Sea urchins reproduce by releasing eggs and sperm into the water, where external fertilization takes place. Once fertilized, the eggs develop into larvae that eventually settle and grow into adult sea urchins. Some species of sea urchins can also reproduce by asexual means, such as splitting or budding.
