Etymology: Chaenodraco: Greek, chaeno = to yawn + Greek, drako = dragon (Ref. 45335).
Eponymy: Dr Edward Adrian Wilson (1872–1912) was an English physician, polar explorer, painter and natural historian. [...] (Ref. 128868), visit book page.

簡短描述 檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 5 - 8; 背的軟條 (總數) : 38 - 42; 臀棘: 0; 臀鰭軟條: 32 - 36. Supraorbital ridge not crenulated. Middle lateral line restricted to caudal peduncle; lower lateral line originating from in front of anal-fin origin to above sixth anal ray. Maxilla extending to below anterior third of eye. Opercular bones with 2 upper and 3 lower spines. Preopercular-mandibular canal not joined to temporal canal. Pelvic fins extending beyond anal-fin origin. In life, pale grey, whitish ventrally. Differentiated by the dorsoventrally oval shape; the prominent distally rounded rostrum, pseudo-rostrum and pseudo-antirostrum; the clearly defined excisura ostii and pseudo-excisura ostii; the acutely constricted collum; and the well developed colliculli.
Ontogeny: The excisura ostii and the pseudo-excisura ostii become deeper and the crista inferior becomes less distinct with an increase in the fish size.
不細齒狀的眶上的脊。 中央側線侷限於尾柄了; 低的側線在臀鰭前面起源方面起源於在第六個臀鰭鰭條之上。 在眼的前三分之一之下顎骨延伸至。 鰓蓋硬骨有兩個上面的與 3個下面的棘。 前鰓蓋骨-顎骨管不連到了暫生管。 腹鰭延伸超過臀鰭起源。 活著時, 白灰色, 微白色的腹地。 藉由有背腹性橢圓形的形狀區別了; 突出的末梢部圓形的喙, 假的-喙與假的-antirostrum; 界線明確的 excisura ostii 與假-excisura ostii; 尖銳地壓縮的 collum; 而且發展良好的 colliculli。 個體發生: 變得比較深的 excisura ostii 與假-excisura ostii 與 crista 下方的變得較不明顯有一個魚大小的增加。

Common in shallower waters of the continental shelf, especially on banks less than 250 m deep in areas where local upwelling increase food supply (Ref. 6390). Postlarvae and pelagic juveniles are also found in the upper 100 m (Ref. 5200). Food consists of fishes and krill. Spawn in winter (Ref. 6390). Larval pelagic phase is long (Ref. 28915). Prey to penguins and seals (Ref. 6390). Utilized as a food fish (Ref. 5200).
大陸棚的常見於較水淺的水域, 尤其在淺堆上在地方湧升流增加食物供應的區域中少於 250 公尺深。 (參考文獻 6390) 食物由魚與磷蝦組成。 冬天時產卵。 (參考文獻 6390) 企鵝與海豹的獵物。 (參考文獻 6390) 作為食用魚.(參考文獻 5200)
