Neopomacentrus flavicauda, commonly known as the Yellowtail Damsel, is a species of damselfish belonging to the family Pomacentridae. These fish are relatively small, vibrant in color, and play a crucial role in the coral reef ecosystems they inhabit.
Description & Characteristics
The Yellowtail Damsel, Neopomacentrus flavicauda, is a relatively small fish with a maximum size of 7 cm (2.8 in). The most striking feature is its bright yellow tail, which contrasts sharply with its blue and yellow body. The body is adorned with a mix of blue and yellow stripes, making it a visually captivating creature. Neopomacentrus flavicauda, like other damselfish, has a compressed body shape and large eyes, aiding in its agility and navigation within the coral reefs.
Habitat and Occurrence
Neopomacentrus flavicauda is a resident of coral reefs, primarily in the Indo-Pacific region. They are found in shallow water environments, typically within a depth range of 1-30 meters (3-98 feet). This makes them commonly sighted in the tropical Indo-Pacific region, specifically the reefs of the Philippines, Indonesia, and parts of the Indian Ocean. These vibrant fish are often observed in the neritic zone, the marine zone extending from the shoreline to the edge of the continental shelf, making their presence a hallmark of these vibrant ecosystems.
Taxonomy
Neopomacentrus flavicauda belongs to the Class: Teleostei, Order: Ovalentaria incertae sedis, and Family: Pomacentridae. This classification positions them among the bony fishes, a diverse group with over 30,000 species. The Order Ovalentaria is a broad group of fish with a complex taxonomic history, while the Family Pomacentridae, or damselfishes, are known for their vibrant colors and territorial behavior, playing a vital role in coral reef health.
Feeding
The Yellowtail Damsel, Neopomacentrus flavicauda, is primarily an herbivore, feeding mainly on algae. Their diet can also include zooplankton and small invertebrates, contributing to their overall role in the delicate balance of the coral reef ecosystem. These feeding habits make them important grazers, helping to maintain the health and growth of coral reefs by controlling algal growth.
