Porpitidae
The Porpitidae are a family of colonial hydrozoans in the order Anthoathecata. They are commonly known as “blue button” or “blue blubbers” due to their striking blue appearance. Porpitidae are characterized by their unique structure, which consists of a central float, called a pneumatophore, surrounded by a colony of polyps. The polyps are responsible for feeding, reproduction, and defense.
Characteristics
The pneumatophore is filled with gas and acts as a buoyant structure, allowing the colony to float on the surface of the ocean. The polyps are attached to the pneumatophore and are specialized for different functions. There are dactylozooids, which are responsible for defense; gastrozooids, which are responsible for feeding; and gonozooids, which are responsible for reproduction. The polyps are connected to each other by a network of canals, which allows for the sharing of nutrients and information.
Environment
Porpitidae are found in warm waters around the world, primarily in tropical and subtropical regions. They are often seen drifting in large numbers along the surface of the ocean.
