Sertularellidae
Sertularellidae is a family of hydroids belonging to the order Leptothecata. These colonial animals are commonly found in marine environments worldwide, forming intricate branching colonies with a characteristically delicate appearance.
Common Names
Sertularellidae are often referred to simply as "sertularellid hydroids." However, common names are not widely used for this family.
Characteristics
Sertularellidae are characterized by several distinct features:
- Branching Colonies: They form branching colonies, which are often encrusting on other substrates.
- Hydrothecae: The hydranths (feeding polyps) are enclosed within protective structures called hydrothecae, which are often tubular and have a distinct shape.
- Gonothecae: Reproductive polyps, called gonophores, are enclosed within structures called gonothecae. These gonothecae can have a variety of shapes and locations on the colony.
- Perisarc: The entire colony is covered in a protective layer called the perisarc, which is often thin and transparent.
Environments
Sertularellidae are common in a variety of marine habitats. They are particularly abundant in:
- Intertidal Zones: On rocks, seaweeds, and other hard surfaces.
- Subtidal Zones: On seafloors, seagrass meadows, and other submerged habitats.
- Estuaries: In brackish water environments, often on pilings and docks.
