A cirriped, also known as a cirripede, is a type of marine crustacean belonging to the class Cirripedia. These animals are commonly referred to as barnacles due to their characteristic hard shells, which resemble miniature barnacles or conical towers. Cirripeds are generally sessile beings, meaning they are permanently attached to a substrate, such as rocks, shells, or man-made structures, throughout their adult life.
The body structure of a cirriped consists of a soft, elongated body enclosed within its protective shell. The shell, made of calcareous plates, is divided into several sections, with an opening at the top through which the animals extend their feeding appendages. These appendages, called cirri, are feathery or hairy in appearance, and are used to filter and catch planktonic organisms that serve as their primary food source.
Cirripeds reproduce through a process called metamorphosis, beginning their lives as free-swimming larvae before settling down and undergoing a complex series of changes to develop into their adult form. They have a highly adaptable nature and can be found in a variety of marine environments, from intertidal zones to deep-sea habitats.
Although often overlooked due to their role as biofoulers on boats and underwater structures, cirripeds play an essential ecological role. They provide a food source for various marine animals, including fish, crabs, and seabirds, and also act as a natural water filtration system by removing organic particles from the water column.
An animal of the class.
