The Slimy Sea Lume, scientifically known as Antillogorgia americana, is a fascinating species of gorgonian coral, distinguished by its distinctive appearance and ecological significance. This captivating organism thrives in the marine environment, playing a vital role in the delicate balance of coral reef ecosystems.
Description & Characteristics
Antillogorgia americana is characterized by its soft, slimy texture and the presence of numerous polyps that extend from the colonial structure. The color of the Slimy Sea Lume can vary, ranging from shades of yellow to brown, often with reddish hues. These corals can attain significant sizes, with some specimens growing up to a maximum length of 1 meter.
Habitat and Occurrence
The Slimy Sea Lume, Antillogorgia americana, is primarily found in the tropical waters of the Caribbean Sea, particularly in areas with strong currents. It is often observed in shallow reef environments, typically at depths ranging from 5 to 30 meters. Antillogorgia americana thrives in marine zones classified as the neritic zone, where sunlight penetrates the water column, enabling photosynthesis.
Taxonomy
The Slimy Sea Lume, Antillogorgia americana, is classified within the phylum Cnidaria, belonging to the Class: Octocorallia, Order: Malacalcyonacea, and Family: Gorgoniidae. This classification reflects the unique characteristics shared by these species, including their eight-fold radial symmetry, the presence of stinging cells (nematocysts), and their colonial nature.
Feeding
Antillogorgia americana exhibits a unique feeding strategy, relying on a combination of sources to obtain sustenance. It can absorb dissolved inorganic substances from the surrounding seawater, including crucial elements like sodium, chloride, calcium, magnesium, potassium, iodine, and phosphorus. Additionally, the coral can absorb dissolved organic substances, contributing to its nutritional needs. Some species of Antillogorgia americana have a symbiotic relationship with zooxanthellae, single-celled algae that reside within their tissues. These algae photosynthesize, providing the coral with a source of energy, and the coral in turn provides the algae with a protected environment and access to essential nutrients. The combination of these feeding mechanisms allows Antillogorgia americana to thrive in its diverse marine environment.
