triangleidens

Triangleidens is a genus of marine ray-finned fish belonging to the family Sparidae, commonly known as porgies. The genus currently contains only one recognized species, Triangleidens dens (Temminck & Schlegel, 1843). This species is native to the western Pacific Ocean, primarily found in the waters around Japan and Korea. Triangleidens dens is characterized by its relatively deep body, which gives it a somewhat triangular appearance when viewed from the side, hence the genus name. Its coloration is typically silvery, with darker fins. They are benthic fish, meaning they inhabit the seabed, and are often found in coastal areas and on continental shelves. Their diet consists mainly of small invertebrates, such as crustaceans and mollusks, which they forage for on the seafloor. Little is extensively documented about the reproductive habits or life cycle of Triangleidens dens, as it is not a species of significant commercial importance. However, like other sparids, they are likely oviparous, releasing eggs and sperm into the water column. The common name "Triangleidens" is derived from the Greek words "triagonon" (triangle) and "odous" (tooth), referring to the shape of the fish and possibly the structure of its teeth, though detailed dental morphology is not widely publicized.
