Corella
Corella is a genus of tunicates belonging to the family Pyuridae. They are commonly known as sea squirts, and are filter feeders that play an important role in marine ecosystems. These animals are sessile, meaning they remain attached to a surface throughout their adult life, and are often found in coastal areas and estuaries.
Characteristics
Corella species are characterized by their barrel-shaped bodies with two siphons, one for inhaling water and the other for exhaling. They have a tough, leathery outer tunic that protects their internal organs. Their size varies depending on the species, but they typically range from a few centimeters to several inches in length. Corella species can exhibit a range of colors, from beige to brown, red, and even bright orange.
Environment
Corella species prefer to live in areas with moderate water currents, allowing them to efficiently filter food from the water. They attach themselves to rocks, piers, and other hard surfaces. They are commonly found in intertidal zones, as well as deeper waters, where they thrive on algae, plankton, and other microscopic organisms.
