Filogranella
Filogranella is a genus of marine annelids, a group of segmented worms that belong to the family Serpulidae. These worms are known for their ability to build calcareous tubes that they live in, contributing to the diverse and colorful environments of marine ecosystems.
Common Names
While Filogranella lacks widely recognized common names, they are sometimes referred to as "tube worms" due to their characteristic tubular structures.
Characteristics
Filogranella species are characterized by their slender, elongated, and often translucent bodies. Their most distinctive feature is their tube-building ability. They secrete a calcareous tube, typically composed of calcium carbonate, which provides them with protection, support, and a stable home. These tubes can be various colors, including white, pink, or yellow, and often exhibit intricate patterns.
These annelids possess a pair of radioles, feather-like structures used for feeding and respiration. The radioles are adorned with numerous cilia, tiny hair-like projections that generate water currents to capture food particles.
Environments
Filogranella species are typically found in marine environments, often attached to rocks, shells, or other solid substrates. They can be found in a variety of habitats, including:
- Intertidal zones
- Subtidal reefs
- Seagrass meadows
- Rocky shores
