SEA URCHIN Meaning and
Definition
-
Sea urchins are marine creatures that belong to the Class Echinoidea and are characterized by their spherical or globular-shaped bodies covered in hard, spiny shells known as tests. These shells are typically made up of tightly interlocking plates or ossicles that provide protection and support for the sea urchin's internal organs.
Sea urchins are found in oceans around the world, mainly in shallow waters but also at abyssal depths. They are part of a diverse group of echinoderms, which also includes starfish, sand dollars, and sea cucumbers. The size of sea urchins varies widely depending on the species, ranging from only a few centimeters to up to 30 centimeters in diameter.
The spines that cover the outer surface of a sea urchin's body serve several purposes. They act as a defense mechanism against potential predators, while also providing stability and maneuverability as the sea urchin moves along the ocean floor. Sea urchins also possess tube feet, which are small, suction cup-like structures used for locomotion and food capturing.
Sea urchins are herbivorous creatures, primarily feeding on algae, seaweed, and dead organic matter. They use their specialized teeth, known as Aristotle's lantern, to scrape and chew their food. As important grazers, sea urchins play a crucial role in maintaining the balance of marine ecosystems by controlling the growth of algae populations.
Sea urchins have been commercially harvested for their gonads, commonly referred to as "uni." These edible parts are considered a delicacy in many cuisines, particularly in Japan. Moreover, sea urchins have also gained popularity in aquariums, where their unique appearance and behavior make them fascinating exhibits.

Etymology of SEA URCHIN
The word "sea urchin" has a straightforward etymology.
The term "urchin" originated in Middle English from the Old French word "orgeuil" meaning "sea urchin". "Orgeuil" itself has further roots in Latin as "auricula" which referred to a small ear-shaped shell or the sea urchin.
In Latin, the term "auricula" can be broken down into "auris" meaning "ear" and the diminutive suffix "-cula" meaning "small" or "of little". The resemblance of the sea urchin's shape to a small ear led to the use of "auricula" to describe the creature.
Over time, "auricula" evolved into "ericius" in Late Latin, and subsequently "urchin" in Middle English. "Sea urchin" specifically denotes the species of the animal found in the ocean.
