Definition
-
Sea urchins are small marine animals belonging to the phylum Echinodermata and the class Echinoidea. These creatures are characterized by their spherical or flattened body shape, covered in a hard exoskeleton with numerous thin, spiny protrusions. They inhabit various oceanic environments, from shallow coastal waters to deep-sea regions, and can be found in all major oceans of the world.
The exoskeleton of sea urchins is comprised of interlocking plates, protecting their soft internal organs. These plates are covered with countless sharp spines that serve numerous functions, including defense, locomotion, and prey capture. Sea urchins move by using their spines to walk or crawl along the ocean floor, while their spines can also be extended and contracted to burrow into soft sediments or grasp onto rocks.
Most sea urchins are omnivorous, feeding on a wide variety of substances like algae, kelp, dead organisms, and even small invertebrates. They possess a unique jaw structure known as Aristotle's lantern, located on the underside of their body, enabling them to scrape and chew food items. Additionally, sea urchins play an important ecological role in controlling algae populations and maintaining the health of their marine habitats.
These remarkable creatures exhibit a diverse range of sizes, shapes, and colorations, depending on their species and environment. Sea urchins have found significance not only in ecological studies but also in gastronomy, as their roe is considered a delicacy in various cuisines worldwide. Due to their intriguing appearance and captivating behavior, sea urchins are often sought after by marine enthusiasts for observation and aquarium keeping.
