Tubeworms are marine invertebrates that belong to the class Polychaeta. They typically live in tubes made of secreted materials or sediment, which provide protection from predators and environmental conditions. Tubeworms can be found in various ocean habitats, including deep-sea vents and shallow waters. These creatures are known for their unique feeding methods. Many tubeworms have specialized structures called feather-like tentacles that help them capture microscopic food particles from the water. Some species, particularly those near hydrothermal vents, rely on symbiotic bacteria to convert chemicals from the environment into energy, allowing them to thrive in extreme conditions.
