The Bald-patch Urchin, scientifically known as Microcyphus rousseaui, is a fascinating echinoderm species found in a variety of marine environments. Its unique characteristics and ecological role make it an intriguing subject of study.
Description & Characteristics
The Microcyphus rousseaui is recognized by its distinctive appearance. This urchin boasts a robust, spherical test, or shell, often with a slightly flattened underside. While the exact size varies, Microcyphus rousseaui generally reaches a maximum diameter of around 5 cm. The test is covered in numerous spines that provide protection and aid in movement. These spines, usually short and sturdy, can exhibit a range of colors, adding to the urchin’s visually captivating nature.
Habitat and Occurrence
The Microcyphus rousseaui is a truly marine species, dwelling in the subtidal, sublittoral, infralittoral, and deep zone of the oceans. Its preferred habitat spans from the lower limit of the intertidal zone (intertidal) to the shelf edge at about 200 m water depth. This makes it a prevalent presence in neritic zones, the area of the ocean that extends from the shoreline out to the edge of the continental shelf.
Taxonomy
The Microcyphus rousseaui belongs to the Temnopleuridae family, which is a group of sea urchins known for their robust tests and often colorful spines. This family, in turn, is part of the Camarodonta order, distinguished by its unique jaw structure. The Camarodonta order falls under the Echinoidea class, which encompasses all the sea urchins.
Feeding
The Microcyphus rousseaui is primarily herbivorous, feeding on a diet that primarily consists of algae. However, it can also be a facultative carnivore, occasionally supplementing its diet with sponges. This adaptability allows the urchin to thrive in diverse environments, utilizing available food sources.
