Yes, metamerism occurs in sea urchins, although it is not as pronounced as in some other marine organisms. Sea urchins exhibit a form of metamerism known as secondary segmentation, where their bodies are organized into a series of repeating units. This segmentation contributes to their overall body plan and aids in their movement and feeding. However, the degree of segmentation is less evident compared to more distinctly segmented animals like earthworms.

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.
Sea otters are secondary consumers. This because sea urchins are primary and sea otters eat sea urchins.
