Etymology: Leptoclinus: Greek, leptos = thin + Greek, klinein, kline = sloping and bed, due to the four apophyses of sphenoid bone (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
生态学
海洋 居于水底的; 深度上下限 2 - 607 m (Ref. 58426). 极; -2°C - 2°C (Ref. 120227); 79°N - 43°N, 180°W - 180°E (Ref. 86838)
Circumpolar: Arctic to temperate waters; northern hemisphere. Arctic Alaska to Sea of Okhotsk, northern Sea of Japan, Unalaska Island in the Aleutian chain and Puget Sound, Washington, USA. North Atlantic: Arctic to Labrador in Canada; along Scandinavia from Skagerrak to Finnmarken, common at Murmansk, White Sea, Iceland and Greenland (Ref. 10006). The Pacific form is sometimes treated as a subspecies Leptoclinus maculatus diaphanocarus (Ref. 51666).
北极圈与太平洋: 阿拉斯加到北极圈鄂霍次克海，日本海北部, 在 Aleutian 的 Unalaska 岛用铁链锁住，而且 Puget 听, 美国在华盛顿州。 北大西洋: 在加拿大的北极圈到拉布拉多; 沿着从史卡基拉克海域到 Finnmarken 的斯堪那维亚半岛，普遍于莫曼斯克，白海，冰岛与格陵兰.(参考文献 10006) 太平洋型式有时被视为一个亚种 斑细鳚〔Leptoclinus maculatus〕 diaphanocarus 。 (参考文献 51666)
Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm 12.5, range 13 - 13 cm
Max length : 20.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 35388)
背棘 (总数) : 57 - 60; 背的软条 (总数) : 0; 臀棘: 1 - 2; 臀鳍软条: 34 - 36. Caudal rounded; lower 5 rays of pectorals greatly lengthened and exserted (Ref. 6885). Color greyish - yellow with dark irregular spots (Ref. 35388).
尾鳍圆的; 胸鳍的低 5个鳍条非常加长了而且突出的。 (参考文献 6885) 色彩灰黄色的有深色的不规则的斑点.(参考文献 35388)
Adults, juveniles, and late postlarvae are found on sandy and mud to pebble bottoms, usually in less than 170 meters (Ref. 2850, 51666, 120227), while early postlarvae are pelagic (Ref. 120227). Food consists of polychaetes and crustaceans (Ref. 10571). They are an important prey for pelagic (as larvae) and benthic (as adults) predators (Ref. 120226). Sexual dimorphism is more pronounced after maturation with males displaying faster somatic growth (Ref. 120226). This marked dimorphism may well be linked with behavioral dissimilarities between males and
females, and is most likely associated with different roles during the breeding season with only adult males have large canines at the tip of upper jaw. It is assumed that males are territorial and defend their spawning sites, whereasfemales guard eggs within her partner’s territory (Ref. 128434).
