Photocorynus

Photocorynus is a genus of marine fish, commonly known as pygmy angelfish, belonging to the family Pomacanthidae. It is found in the Indo-Pacific region, specifically in coral reefs and rocky areas, between the depths of 2-200 meters.

There are 11 species within the genus, with the most widespread being Photocorynus longicirrhus. Members of this genus are characterized by their elongated bodies, often reaching a maximum length of about 12 centimeters. They have a bright green to blue-green color with yellow and red stripes or spots. Their fins are long, pointed, and slender, with lateral lines present.

The slender bodies of Photocorynus are coated in small scales, while their skin on the body has small protrusions called tubercles. The scientific understanding of the taxonomic position of species within this genus suggests they may be distinct enough to be moved away from the genus Centropyge.

Photocorynus has a close relationship with some species of corals, making it part of a community of marine animals that live with corals in the deserts of the deep oceans and shallow waters. In terms of growth, these fish are still undergoing study by scientists to gain better insight. No work on reproduction or basin size has been conducted among marine biologists.

Overall, the scientific community's understanding of Photocorynus is growing but remains underdeveloped. Research on the genus is necessary to fill gaps in its taxonomy, ecology, and more, to ensure accurate and comprehensive studies.
