TUNICATE Meaning and
Definition
-
A tunicate refers to any of the marine animals belonging to the phylum Chordata, subphylum Tunicata. Also known as urochordates or sea squirts, these organisms are characterized by their unique sac-like body structure enclosed within a leathery or gelatinous tunic, which gives them their common name. Tunicates are found in both shallow and deep ocean waters, often attached to rocks, corals, or other substrates.
The anatomy of a tunicate is composed of two main parts: the tunic, which is their outer protective covering, and the body itself. The body consists of a large oral siphon and a smaller atrial siphon, which allow water to pass through the organism. Tunicates feed by filtering microscopic particles and plankton from the water using ciliated structures called pharyngeal slits.
While adult tunicates are mostly sessile, some species have a motile larval stage that swims freely in the water. These larvae possess a notochord, a defining characteristic of chordates, which disappears as they metamorphose into the adult form.
Tunicates come in various shapes, sizes, and colors, ranging from solitary individuals to colonial organisms. Their ecological importance is significant as they contribute to the marine food web by both consuming and being consumed by other organisms. Additionally, tunicates can serve as indicators of water quality due to their sensitivity to environmental changes. Studies on tunicates have provided valuable insights into the evolutionary history and development of chordates, making them a subject of interest for scientists and marine enthusiasts alike.
