Original description: Enneapterygius pallidoserialis Fricke, 1997 - Type locality: Putic Island, northwestern side (Cuyo Island), Palawan Province, Philippines, 10°55'05"N, 121°02'03"E, depth 0-4.5 meters.

Adults are found in shallow waters and outside barrier reefs. Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites. Larvae are planktonic which occur primarily in shallow, nearshore waters. Sexes differ in the darker colouration of the male, especially the body and vertical fins dark brown or gray.
