Etymology: Pteroidichthys: Greek, pteron = wing, fin + Greek, ichthys = fish (Ref. 45335). More on author: Bleeker.
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 3 - 43 m (Ref. 106976). Tropical; 37°N - 27°S, 107°E - 178°W (Ref. 106976)
Indo-West Pacific: from southern Japan (except Ryukyu Islands), Vietnam, Indonesia, Papua New Guinea, Fiji, Australia, Taiwan, India, and the Red Sea.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 12.0 cm TL male/unsexed; (Ref. 48635)
soft rays: 6. This species is distinguished by the following characters: A II,6; dorsal-fin spines flexible, bend easily under slight pressure; snout is relatively short, 12.3-17.0% (mean 14.3%) of SL, it is shorter than postorbital length; posterior margin of maxilla reaching to or extending beyond vertical through middle of pupil; the distance between tips of lateral lacrimal and the first suborbital spines is shorter than or subequal to that between tips of first and second suborbital spines; no supplemental preopercular spine; tentacles on supraocular and posterior lacrimal spines are well developed, their lengths greater than orbit diameter; trunk and fins with numerous tentacles; lateral lacrimal and suborbital spines are poorly developed, indistinct, usually tiny spines and often bony protuberances without pointed tips; absence of distinct black blotch on soft-rayed portion of dorsal fin (Ref. 106976).
This species lives primarily in algae or soft-bottom habitats (Ref. 48635); it can be easily overlooked because of its superb camouflage (Ref. 54980). Solitary among weed or on mud bottoms (Ref 90102).
