Etymology: Asterropteryx: Greek, a = with + Greek, sterros, -a, -on = consistent + Greek, pteryx = fin (Ref. 45335); ovata: Name from Latin 'ovata' meaning egg-shaped, refers from the large ovoid black spot on the base of caudal fin.
Umwelt: Milieu / Klimazone / Tiefenbereich / Verbreitungsgebiet
Ökologie
seewasser demersal; tiefenbereich 15 - 40 m (Ref. 75136). Tropical
Western Pacific: Sulawesi (Indonesia) and Ponape (Caroline Islands), including Japanese waters; probably more widely distributed in the area and the Indian Ocean.
Größe / Gewicht / Alter
Geschlechtsreife: Lm ?  range ? - ? cm
Max length : 2.7 cm SL Männchen/unbestimmt; (Ref. 75136)
Rückenflossenstacheln (insgesamt) : 7; Rückenflossenweichstrahlen (insgesamt) : 9 - 10; Afterflossenstacheln: 1; Afterflossenweichstrahlen: 8 - 9. This species differs from the other species of the spinosa complex in having the following set of characters: cheek spines 3-6; largest cheek spine slender obviously longer than other spines, length 2.6-6.3% SL; a pupil- or eyesized ovoid black spot on base of caudal fin (extending anteriorly to third mid-lateral scale before posterior margin of hypural); head, body and dorsal fins when alive or fresh has numerous orange speckles; first dorsal fin with no distinct black spot (Ref. 75136); characterized further by having prolonged fourth dorsal spine, forms long filament in adult; longitudinal scale series 22-24; ctenoid predorsal and body scales; cycloid scales in cheek, opercle, pectoral-fin base and prepelvic area; rounded caudal fin; depth of body 3.2-3.7 in SL (Ref. 90102).
Body shape (shape guide): elongated; Cross section: compressed.
Occurs in coral-reef slopes in the protected bays, found solitary on muddy or sandy-mud bottoms with dead-coral rubbles under the heavy growth of corals (Ref. 75136).
