Etymology: Pterapogon: Greek, pteron = wing, fin + Greek, pogon = beard (Ref. 45335).
Eponymy: Dr Walter Alexander Kaudern (1881–1942) was a Swedish ethnographer and zoologist. [...] (Ref. 128868), visit book page.
Environnement : milieu / zone climatique / profondeur / gamme de distribution
Écologie
marin démersal; profondeur 0 - 16 m (Ref. 90102), usually 1 - 2 m (Ref. 9936). Tropical; 1°S - 2°S, 123°E - 124°E
Western Pacific: Apparently restricted to Banggai Islands, Indonesia. Also found in several small islands off nearby eastern Taliabu Island and Luwuk vicinity (Ref. 90102). Threatened by extinction due to collection for the aquarium trade (Ref. 27438, 35396).

Body shape (shape guide): short and / or deep; Cross section: compressed.
Common around the jetty, in silty sand bottoms with seagrass (Enhalus acoroides). Associated with Diadema setosum, the long-spined sea urchins. Individuals of 2 to 60 hover directly above the urchins, with the younger ones about 2-3 cm SL staying closer to the urchins. The fish retreat among the spines when threatened. Probably feed on small benthic and planktonic crustaceans at night. Male incubates the eggs until hatching; the large egg about 2.5 mm in diameter, with the young remaining within the mouth cavity for undetermined period after hatching (Ref. 9936, 48635). Newly hatched larvae have no planktonic period (Ref. 35886). Juveniles also use anemones for protection (Ref. 45560, 48635). Has been reared in captivity (Ref. 35417).
The male takes the eggs into its mouth where these and the larvae remain until young fish of about 8mm SL are released. Distinct pairing during courtship and spawning (Ref. 205). Also Ref. 240.
