Aplidium benhami is a colonial tunicate species, commonly known as a sea squirt, belonging to the family Polyclinidae. This species is distinguished by its unique morphological characteristics and its prevalence in specific marine environments.
Description & Characteristics
Aplidium benhami colonies, composed of numerous zooids, can reach a maximum size of several centimeters. The zooids are typically arranged in clusters or lobes, giving the colony a distinctive appearance. The surface of the colony is often covered in small, wart-like structures, adding to its characteristic texture.
Habitat and Occurrence
Aplidium benhami is primarily found in the intertidal and subtidal zones, typically inhabiting rocky shores and reefs. These colonies thrive in a variety of marine environments, demonstrating their adaptability. While they can be found in both the epipelagic and mesopelagic zones, they are most commonly observed in the shallow depths of the neritic zone.
Taxonomy
Aplidium benhami belongs to the Class Ascidiacea, which encompasses all tunicates. Within this class, it is categorized within the Order Aplousobranchia, which comprises sea squirts with a simple branchial sac. This species is further classified within the Family Polyclinidae, a family characterized by colonial tunicates with a distinct arrangement of zooids.
Feeding
Aplidium benhami, like other tunicates, are filter feeders. They utilize their siphons to draw in seawater, extracting microscopic food particles such as plankton and algae. The water is then expelled through a separate exhalant siphon, completing the feeding process.
