Eusynstyela tincta is a species of tunicate belonging to the family Styelidae. These solitary ascidians are commonly found in marine environments, particularly in the intertidal zone.
Description & Characteristics
Eusynstyela tincta is a relatively small tunicate, with individuals typically reaching a maximum size of around 5 centimeters in length. The species is characterized by its distinctive coloration, often exhibiting a combination of hues such as brown, grey, and orange. The body of Eusynstyela tincta is covered in a tough, leathery tunic that provides protection and support.
Habitat and Occurrence
Eusynstyela tincta is a common inhabitant of the intertidal zone, primarily occurring in rocky habitats and on the underside of piers. They are frequently found attached to various surfaces such as rocks, seaweed, and even shells. This species prefers locations with moderate wave action and moderate to high water flow. Eusynstyela tincta can be found in both the epipelagic and mesopelagic zones, typically in depths ranging from the surface to 100 meters. This species exhibits a wide geographic distribution, occurring along the coasts of the eastern Pacific Ocean, including California, British Columbia, and Alaska.
Taxonomy
Eusynstyela tincta belongs to the phylum Chordata, class Ascidiacea, order Stolidobranchia, and family Styelidae. This classification places Eusynstyela tincta within a group of marine invertebrates that are characterized by their filter-feeding habits and sac-like bodies.
Feeding
Like other ascidians, Eusynstyela tincta is a filter feeder. It draws water into its body through an incurrent siphon and filters out food particles, primarily phytoplankton, using its pharyngeal gill slits. The filtered water is then expelled through an excurrent siphon. Eusynstyela tincta plays a crucial role in marine ecosystems as a primary consumer, contributing to the flow of energy and nutrient cycling within the food web.
