生態學
; 淡水 居於水底的; 深度上下限 ? - 16 m (Ref. 1998). 溫帶; 59°N - 34°N
North America: widespread with highly disjunct distribution in Canada and USA. The former Blue Ridge race of the Atlantic slope of the Appalachian Mountains is now recognized as a distinct species Cottus caeruleomentum.
北美洲: 在加拿大與美國中有高度地非連續分布廣泛分佈。 Appalchian 山的大西洋斜坡的先前藍色脊比賽現在被鑑定為一個不同的種 Cottus caeruleomentum 。
大小 / 重量 / 年齡
Maturity: Lm ? range ? - ? cm
Max length : 15.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 5723); common length : 8.4 cm TL 雄魚/尚未辨別雌雄; (Ref. 12193); 最大年齡: 2.00 年 (Ref. 12193)
Adults occur in rubble and gravel riffles, less often in sand-gravel runs of headwaters, creeks and small rivers. Also found in springs and their effluents and rocky shores of lakes (Ref. 1998, 10294). Feed mainly on aquatic insect larvae, but also on crustaceans, annelids, fishes, fish eggs, and plant material (Ref. 1998, 10294). Spawn in the spring (Ref. 1998). A male guards the cluster of eggs laid by different females (Ref. 1998). Neither anterolateral glandular groove nor venom gland is present (Ref. 57406).
成魚出現在瓦礫與碎石激流, 較不常見於沙子-礫石河川源頭,小溪與小河的小支流。 也發現於泉水與湖的其溢流與岩岸。 (參考文獻 1998,10294) 主要捕食水生的昆蟲幼生, 也捕食甲殼動物，環節動物，魚，魚卵與植物.(參考文獻 1998,10294) 產卵於春天中。 (參考文獻 1998) 一隻雄魚保衛被不同雌性放置的卵的群。 (參考文獻 1998) 既不是前外側的腺凹槽也不是毒液腺存在.(參考文獻 57406)
Life cycle and mating behavior
成熟度 | 繁殖 | 產卵場 | 卵 | 孕卵數 | 仔魚
Male selects a nesting site under a rock of ledge. Male entices a female to enter the nest. Female deposits eggs on the upper surface of the rock and leaves or is driven out of the nest. Eggs are deposited by different females. The male guards the eggs from predators and maintains a natural current flow (Ref. 1998).
