Eudendrium
Eudendrium is a genus of colonial hydroids in the family Eudendriidae. These marine invertebrates are commonly found in coastal waters around the world, with a particularly high diversity in temperate regions. They are characterized by their branching polyp colonies, which are typically attached to hard substrates like rocks, seaweeds, and shells.
Common Names
While no single common name exists for the genus Eudendrium, individual species may have specific names, such as the "branching hydroid" or "feather hydroid," based on their appearance.
Characteristics
Eudendrium species share several key characteristics:
- Colonial: They live in colonies of interconnected polyps.
- Branching: Their colonies exhibit branching patterns, resembling small trees or bushes.
- Polymorphism: Colonies contain different types of polyps, including feeding polyps (gastrozooids) and reproductive polyps (gonozooids).
- Hydrostatic Skeleton: They lack a rigid skeleton and rely on water pressure for support.
- Small Size: Most Eudendrium species are only a few centimeters in height.
Environment
Eudendrium species are typically found in shallow, coastal waters, attached to various substrates. They thrive in areas with moderate water currents and relatively low levels of pollution. Some species can tolerate a range of salinities, while others are more restricted to specific habitats.
