POLYCLADIDA Meaning and
Definition
-
Polycladida is a class of flatworms belonging to the phylum Platyhelminthes. They are commonly known as polyclads or flatworms, and they are characterized by their flattened body shape and vibrant coloration. Polyclads have a soft, unsegmented body that can range in size from a few millimeters to several centimeters in length. They have a distinct bilateral symmetry, with a flat ventral surface and a slightly convex dorsal surface.
Polyclads are free-living marine organisms that can be found in a wide range of marine habitats, from intertidal zones to coral reefs and even deep-sea environments. They are typically found in tropical and subtropical regions worldwide. One of their most distinguishing features is a network of branched gastrovascular canals that run throughout their body, which is used for respiration, excretion, and digestion.
Despite their small size, polyclads are highly predatory and feed on a variety of small invertebrates, including small crustaceans, mollusks, and worm-like organisms. They have a muscular pharynx that extends out of their body to capture and consume their prey. Polyclads have a remarkable regenerative capacity and are able to regenerate lost body parts, including their entire body if necessary.
In conclusion, Polycladida is a class of flatworms characterized by a flattened body shape, vibrant coloration, and a network of gastrovascular canals. They are free-living marine organisms that can be found in various marine habitats worldwide. Polyclads are highly predatory, feeding on small invertebrates, and possess a remarkable regenerative capacity.
