Neoglyphidodon

Neoglyphidodon is a genus of damselfish in the subfamily Glyptodontinae. These fish are found in the Indo-Pacific region. The genus was established by Smith-Vaniz in 1976.

Species within Neoglyphidodon are characterized by their bright coloration and the presence of a single, prominent spine on the caudal peduncle. They are typically small, schooling fish that inhabit coral reefs. Neoglyphidodon species are often territorial, especially during breeding season. Their diet consists mainly of algae and small invertebrates.

The genus Neoglyphidodon is distinguished from its close relatives by specific anatomical features, including the number of gill rakers and the shape of the preorbital bone. Their ecological role on the reef is significant, as they contribute to grazing pressure on algae and serve as a food source for larger predatory fish.

Currently, the genus Neoglyphidodon contains several recognized species. These species can vary in their specific geographic distribution and preferred microhabitats within the reef ecosystem. Conservation status for Neoglyphidodon species is generally considered good, although local pressures from habitat degradation and overfishing can pose threats. Further research is ongoing to better understand the population dynamics and behavioral ecology of these damselfish.
