Etymology: Enneapterygius: Greek, ennea = nine times + Greek, pterygion = little fin (Ref. 45335). More on authors: Jordan & Seale.
The junior synonym Enneapterygius altipinnis Clark, 1980 is considered as valid species in CofF ver. January 2018 following Holleman, et al. 2012 (Ref. 88983:41). Its synonymy under the current species will be removed.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 0 - 55 m (Ref. 90102). Tropical
Indo-West Pacific: Red Sea and East Africa (Ref. 33390) to the Philippines and Taiwan (Ref. 27223), south to Papua New Guinea, Australia, then east to New Caledonia, Vanuatu, Fiji, the Solomon Islands, and American Samoa.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 4.0 cm TL male/unsexed; (Ref. 48636)
(total): 13 - 16;
soft rays: 15 - 20. Identified by the tall first dorsal fin that is white in males (Ref. 48636). Large individuals may have conspicuous dark spot on upper middle of second dorsal fin connected to a band extending down the sides as well as about 5 darker bars on body and red snout and lower head (Ref. 37816).
Adults are found in various reef habitats, but often on sponges or reef outcrops (Ref. 48636). Also found in intertidal pools (Ref. 13227) and on corals and rocks (Ref. 37816). They feed on zooplankton (Ref. 48636). Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114). The most common and most widely distributed among Enneapterygius species (Ref. 90102). Minimum depth reported from Ref. 13227.
