Info
Bryozoans like Bougainvillia muscus occur in two manifestations, the initially free-swimming medusa and later the sessile, epiphytic polyp, which may well resemble corals.
The medusa with its hemispherical umbrella reaches a size / diameter of 2 - 4 mm, the medusa has four small, oval marginal, dark reddish brown, purple or yellowish, sometimes with greenish tinge tentacular tubercles, each with a group of 4 - 9 long and firm tentacles of one kind.
The sessile hydroid polyp produces new medusae in spring, summer and fall, which can be encountered until December.
Habitat: The sessile hydroid polyp is encountered from shallow water to very great depths, it is found on rock, algae / aquatic plants and animal bentos e.g. mussels.
In contrast to fish and many corals, hydroid polyps are still among the really poorly studied marine animals.
