生態学
海 関連する礁; 深さの範囲 0 - 12 m (Ref. 86942). Tropical; 16°N - 24°S
Indo-Pacific: East Africa to the Line and Society Islands, north to Mariana Islands, south to the southern Great Barrier Reef; throughout Micronesia. Likely at Seychelles (Ref. 1623).
サイズ / 重さ / 年齢
Maturity: Lm ? range ? - ? cm
Max length : 7.5 cm TL オス/雌雄の選別がない; (Ref. 90102)
背面の脊椎 (合計) : 10 - 11; 背鰭 (合計) : 14 - 16. Has a tall dorsal fin and small tufts below the chin (Ref. 48636). Resembles P. thepassii and P. variabilis but usually has fewer total dorsal fin elements (Ref. 37816).
Adults occur solitary (Ref. 90102) usually over sandy areas of reef flats and shallow lagoons. Small juveniles were found below the upside-down jelly Cassiopea that moves over sandy substrates providing safe travel (Ref. 48636). Eggs are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Females nest in empty mollusk shells (Ref. 1602). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).
