Pocillopora aliciae, also known as the Aliciae Branching Coral, is a species of stony coral found in the Indo-Pacific region. Its distinctive branching structure and vibrant coloration make it a captivating sight in the underwater world.
Description & Characteristics
Pocillopora aliciae exhibits a characteristic branching morphology, with its colonies forming intricate networks of interconnected branches. These branches can grow to a significant size, reaching up to several meters in length. The coral polyps, responsible for building the calcium carbonate skeleton, are small and numerous, contributing to the intricate appearance of the colony. Its color palette encompasses a range of hues, including brown, green, and yellow, with shades that often vary depending on the environmental conditions and symbiotic algae present.
Habitat and Occurrence
Pocillopora aliciae thrives in shallow, tropical waters, typically inhabiting the Intertidal (Eulittoral) zone, the intertidal zone between the high and low tide lines characterized by the alternation of low and high tides. This means they are well-adapted to the fluctuating conditions of this zone, including exposure to air during low tide and submersion during high tide. They are commonly found in reef environments, where they contribute to the complex structure and diversity of the ecosystem.
Taxonomy
The species Pocillopora aliciae belongs to the Class: Hexacorallia, Order: Scleractinia, and Family: Pocilloporidae. Hexacorallia encompasses a diverse group of corals characterized by their six-fold symmetry. Scleractinia, also known as stony corals, are distinguished by their hard, calcium carbonate skeletons. The Pocilloporidae family includes branching and encrusting corals, many of which exhibit a distinctive morphology and ecological role in coral reefs.
Feeding
Pocillopora aliciae, like many other corals, employs a mixed feeding strategy. They obtain nutrients from two primary sources: plankton and symbiotic algae known as zooxanthellae. Plankton, microscopic organisms drifting in the water column, are captured by the coral polyps using their tentacles. The zooxanthellae reside within the coral’s tissues and photosynthesize, providing the coral with essential nutrients. The relationship between Pocillopora aliciae and its zooxanthellae is mutually beneficial, with the coral providing shelter and nutrients to the algae, while the algae produce oxygen and carbohydrates for the coral.
