Perophora hutchisoni is a species of tunicate belonging to the family Perophoridae. It is commonly found in the marine environment and is characterized by its unique morphology and ecological role.
Description & Characteristics
Perophora hutchisoni is a colonial tunicate, meaning it exists as a group of interconnected individuals called zooids. These zooids are typically small, ranging in size from a few millimeters to a centimeter. The colonies often have a branching or tree-like structure, with individual zooids attached to a common stalk. Each zooid is enclosed in a translucent tunic, giving the colony a delicate and ethereal appearance.
Habitat and Occurrence
Perophora hutchisoni is a widespread species, found in a variety of marine environments. It is particularly common in shallow coastal waters, including estuaries and bays. These tunicates are often observed attached to seaweeds, rocks, and other submerged structures. They are typically found in the intertidal zone, meaning they are exposed to both air and water as the tide changes.
Perophora hutchisoni is considered a benthic species, meaning it lives on the seafloor or in close association with the bottom substrate. It is also a common inhabitant of the neritic zone, which is the coastal region of the ocean extending from the shoreline to the edge of the continental shelf.
Taxonomy
Perophora hutchisoni is classified within the phylum Chordata, a group that includes all vertebrates, as well as tunicates and cephalochordates. This species belongs to the Class Ascidiacea, which comprises all sea squirts. Further, Perophora hutchisoni is classified within the Order Phlebobranchia, a group characterized by having a single, simple branchial sac. Finally, this species belongs to the Family Perophoridae, a family of colonial ascidians.
Feeding
Perophora hutchisoni is a filter feeder, using its pharyngeal basket to collect food particles from the surrounding water. This basket is lined with cilia, which create a current that draws water into the zooid’s mouth. As the water passes through the basket, microscopic food particles, such as phytoplankton and zooplankton, are trapped by a layer of mucus. These trapped particles are then transported to the digestive tract, where they are broken down and absorbed.
