Plectroglyphidodon
Plectroglyphidodon is a genus of damselfishes within the family Pomacentridae. These fishes are commonly known as “damsels” or “demoiselles.” They are found in the tropical waters of the Indo-Pacific region, particularly in coral reefs and lagoons. There are currently 13 recognized species within this genus, each displaying a unique combination of colors and patterns.
Characteristics
Plectroglyphidodon species are generally small, reaching a maximum length of around 15 cm. They are distinguished by their elongated, compressed bodies, which are typically brightly colored with vibrant hues of blue, yellow, orange, and black. Their bodies are adorned with intricate patterns, often including stripes, spots, and lines. The most defining characteristic of this genus is the presence of a prominent, vertical black band that extends from the eye to the base of the tail. This band can be narrow or broad, and may vary in intensity depending on the species and the individual.
Environments
Plectroglyphidodon damsels are primarily found in shallow, coral-rich waters, typically residing in lagoons, reefs, and rocky shores. They prefer areas with abundant coral cover and a diverse array of algae, as they feed mainly on algae and other invertebrates. These damsels are territorial and will defend their feeding grounds, displaying aggressive behaviors towards intruders, including other fish species.
