背的软条 (总数) : 10 - 11; 臀鳍软条: 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.)
着色的褐色背面与橘色的-腹地的粉红色; 鳍有在边缘以灰白色区块对比的深灰色区块。 下唇嘴部具有延长分叉的乳突。 被放置在每一 2个鳞片之间的侧线孔管取代 2:1:2 的普遍图案。 (参考文献 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 的侧线鳞片图案 (，那是,2个鳞片: 孔,2个鳞片: 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).
栖息于海岸的沙栖息地 , 海湾与河口在那里它们保持埋藏状态在白天期间。 也发现于较深的水域 160-678 公尺。 稚鱼，亚成鱼与成鱼出现在水浅的沿岸区域; 成鱼也居住于深的大陆棚及大陆斜坡区域，而且孤立的外海达到稳定水平, 而且能够两者之间移动.(参考文献 48492) 与第一个新的古苏格兰的记录以一为依据成熟的母鱼与一花费了雄鱼, 捕获在 960-1233 公尺深, 超过 700个海浬从最靠近认识族群, 它被假定成鱼 sandfish 沿着大洋性的脊移动产卵于南方的新古苏格兰的水域中.(参考文献 48492)
