簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 10 - 11; 臀鰭軟條: 7 - 8; 脊椎骨: 64 - 66. Pigmented brown dorsally and orange-pink ventrally; fins have dark gray patches contrasting with pale gray patches at the margins. Lower lip of mouth with elongated forked papillae. Lateral line pore tubes positioned between every 2 scales instead of the common pattern of 2:1:2 (Ref. 38037). Caudal vertebrae (= pleural caudal vertebrae + ural caudal vertebrae) 12 + 1. Lateral line scale pattern of 2:2:2 (that is, 2 scales: pore, 2 scales: pore, etc.)
著色的褐色背面與橘色的-腹地的粉紅色; 鰭有在邊緣以灰白色區塊對比的深灰色區塊。 下唇嘴部具有延長分叉的乳突。 被放置在每一 2個鱗片之間的側線孔管取代 2:1:2 的普遍圖案。 (參考文獻 38037) 尾部的脊椎骨 (= 胸膜的尾部脊椎骨 + ural 尾部的脊椎骨)12+1. 2:2:2 的側線鱗片圖案 (，那是,2個鱗片: 孔,2個鱗片: 孔, 等等。)
Inhabits coastal sandy habitats , bays and estuaries where they remain buried during the day. Also found in deeper water 160-678 m. Juvenile, subadult and adult occur in shallow coastal areas; adults also inhabit deep shelf and slope areas and isolated offshore plateaus, and are capable of moving between the two (Ref. 48492). With the first New Caledonian record based on one ripe female and one spent male, captured at 960-1233 m depth, over 700 nautical miles from the nearest known populations, it is hypothesized that adult sandfish migrates along oceanic ridges to spawn in southern New Caledonian waters (Ref. 48492).
棲息於海岸的沙棲息地 , 海灣與河口在那裡它們保持埋藏狀態在白天期間。 也發現於較深的水域 160-678 公尺。 稚魚，亞成魚與成魚出現在水淺的沿岸區域; 棲息於深的大陸棚及大陸斜坡區域與孤立的外海成魚也達到穩定水準, 而且能夠兩者之間移動。 (參考文獻 48492) 與第一個，以一個成熟的母魚為依據的新古蘇格蘭的記錄與一花費了最靠近被認識族群的在 960-1233 公尺深被取得的雄魚，超過 700個海浬從, 它被假定成魚 sandfish 沿著大洋性的脊移動產卵於南方的新古蘇格蘭的水域中。 (參考文獻 48492)
