The Yellowband Fusilier, Goldband Fusilier, or Yellow-band Fusilier (Pterocaesio chrysozona) is a species of marine fish belonging to the fusilier family (Caesionidae). They are a common sight in the Indo-Pacific region, known for their striking yellow bands that adorn their silver bodies.
Description & Characteristics
The Pterocaesio chrysozona is a relatively small fish, reaching a maximum size of 21.0 cm. They exhibit a streamlined, fusiform body shape, typical of fusiliers. The most distinctive feature of this species is the prominent yellow band that extends horizontally across the body just below the dorsal fin. The rest of the body is a silvery-white color, with a slightly darker shade on the back. They have small mouths and relatively small scales, and their fins are a pale yellowish color.
Habitat and Occurrence
The Yellowband Fusilier (Pterocaesio chrysozona) is typically found in coral reefs and lagoons, inhabiting the shallow waters of the Indo-Pacific region. They prefer areas with abundant coral cover and can be seen at depths ranging from 2.0 to 25.0 meters. These fusiliers are often observed in large schools, sometimes in association with other species of fusiliers. They are a common inhabitant of the tropical marine zone, where they contribute to the vibrant diversity of coral reef ecosystems.
Taxonomy
The species Pterocaesio chrysozona belongs to the Class: Teleostei, Order: Eupercaria incertae sedis, and Family: Caesionidae. This scientific classification places it within a large group of ray-finned fishes that exhibit diverse adaptations for a wide range of aquatic environments.
Feeding
The Yellowband Fusilier (Pterocaesio chrysozona) is a planktivore, feeding primarily on small zooplankton, including crustaceans and larval fish. They are often observed feeding in mid-water, using their small mouths to filter plankton from the water column. Their diet also includes frozen food, both large and small sorts, indicating a flexible foraging strategy.
