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.
Sea urchins are found generally in the sea, however they can also be found in/on rock pools or areas near to the sea.
