Phellia
Phellia is a genus of sea anemones in the family Actiniidae. They are characterized by their relatively small size, slender column, and distinct oral disc. The genus is widely distributed in the Indo-Pacific region, typically found in shallow, rocky reefs and coral ecosystems.
Common Names
Common names for species within the genus Phellia are not widely used and often vary regionally. Some species, like Phellia floscula, are simply referred to as "sea anemones."
Characteristics
Phellia anemones are typically small, with column lengths ranging from a few millimeters to a few centimeters. Their column is slender and may be smooth or covered in small bumps. The oral disc is distinct and typically has a variety of colorful patterns. They have a single mouth opening surrounded by tentacles, which are typically short and numerous.
These anemones are carnivores, feeding on small invertebrates and plankton. They use their tentacles to capture prey and paralyze it with nematocysts, stinging cells that contain toxins. The food is then transported to the mouth for digestion.
Environments
Phellia anemones are found in a variety of marine environments, including:
- Shallow, rocky reefs
- Coral ecosystems
- Seagrass beds
- Mangrove forests
They are typically found in areas with strong currents and plenty of food sources. They can also be found in association with other invertebrates, such as sponges and corals.
