Characteristics
Polyclinids are characterized by their colonial nature, with individuals known as zooids living in close association within a shared gelatinous tunic. Zooids are typically small, ranging from a few millimeters to a few centimeters in length. Each zooid possesses a siphon for inhaling water, another for exhaling water, and a digestive system for filtering food particles. They often exhibit a distinctive pattern of color and shape, which varies depending on the species.
Environments
Polyclinids are found in a variety of marine habitats, including:
- Intertidal zones
- Subtidal zones
- Coral reefs
- Deep-sea environments
They prefer hard substrates, such as rocks, shells, and seaweeds, where they can attach themselves. Some species are also found on soft sediments, where they can create burrows or form loose colonies.
