Any of numerous, usually colonial marine coelenterates of the order Hydroida, having a polyp rather than a medusoid form as the dominant stage of the life cycle. Hydroids have a simple cylindrical body with a mouthlike opening surrounded by tentacles.

The most well-known hydroids are the hydras (genus Hydra), which are atypical in being both freshwater and solitary.
