The Striated Surgeonfish, scientifically known as Ctenochaetus striatus, is a vibrant and intriguing species found in the coral reefs of the Indo-Pacific region. This fish is easily recognizable by its distinctive coloration and unique body shape.
Description & Characteristics
The Ctenochaetus striatus is a relatively small fish, with a maximum size reaching 26.0 cm. It is characterized by its elongated, compressed body and a striking color pattern. The fish is typically a deep blue color, adorned with bright yellow vertical stripes that extend from the head to the tail. Its dorsal fin is long and continuous, while the anal fin is located near the tail. The most notable feature of the Ctenochaetus striatus is its sharp, scalpel-like spine located at the base of its tail, hence the common name “surgeonfish.” This spine, used for defense, is retractable and can be used to inflict a painful wound.
Habitat and Occurrence
The Ctenochaetus striatus thrives in the Subtidal, sublittoral, infralittoral, deep zone of the oceans from the lower limit of the intertidal zone (intertidal) to the shelf edge at about 200 m water depth. neritic. This fish is commonly found in coral reefs, particularly in areas with abundant algae growth. It prefers clear, warm waters and can be found at depths ranging from 0.0 to 60.0 meters. Their distribution is primarily restricted to the Indo-Pacific region, from the Red Sea to the Eastern Pacific.
Taxonomy
The species Ctenochaetus striatus belongs to the Class: Teleostei, Order: Acanthuriformes, and Family: Acanthuridae. The family Acanthuridae, known as surgeonfishes or tangs, comprises over 90 species found in tropical and subtropical waters worldwide. The Ctenochaetus striatus is one of the most easily recognized and studied species within this diverse group.
Feeding
The Ctenochaetus striatus is an herbivore, with a diet consisting primarily of algae. They graze on various forms of algae, including detritus, phytoplankton, and nori-algae. Their feeding habits are crucial for maintaining the balance of the coral reef ecosystem by controlling the growth of algae. In addition to algae, they also consume other food sources such as brine shrimps, flakes, frozen food (large sort), and krill.
