Pacifigorgia
Pacifigorgia is a genus of soft corals in the family Alcyoniidae. They are commonly known as sea whips or gorgonians, and are characterized by their branching, whip-like structure. Pacifigorgia species are found in the Pacific Ocean, primarily along the coast of North America. These corals are colonial organisms, consisting of numerous tiny polyps that are connected by a network of tissue.
Characteristics
Pacifigorgia corals are typically brightly colored, often displaying hues of red, orange, yellow, or purple. They have a distinctive, branching morphology, with branches that can be either short and stubby or long and slender. The polyps are small and extend from the branches, capturing food from the surrounding water. The surface of the coral is often covered in spicules, which are microscopic, needle-like structures that provide support and protection.
Environments
Pacifigorgia species inhabit a variety of marine environments, including rocky reefs, kelp forests, and sand bottoms. They prefer areas with moderate water flow and ample sunlight. They are typically found at depths ranging from the intertidal zone to about 100 meters.
Distribution
Pacifigorgia corals are found in the Pacific Ocean, with a distribution that extends from Alaska to Baja California. They are most common along the western coast of North America, where they are a significant component of the local marine ecosystem.
Species
There are several recognized species within the genus Pacifigorgia, including:
- Pacifigorgia cf. rubiformis
- Pacifigorgia cf. stellata
- Pacifigorgia cf. violacea
