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

生物学特性     字汇 (例如 epibenthic)

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).

出现于瓦砾与碎石激流, 较不常见于沙子-砾石河川源头,小溪与小河的小支流。 也发现于泉水与湖的其溢流与岩岸。 主要吃水生的昆虫幼生, 也捕食甲壳动物,环节动物,鱼,鱼卵与植物.(参考文献 1998) 产卵在春天。 (参考文献 1998) 既不是前外侧的腺凹槽也不是毒液腺存在.(参考文献 57406)

Life cycle and mating behavior Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 仔鱼

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). Also Ref. 53335.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

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00676 (0.00300 - 0.01523), b=3.17 (2.98 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
营养阶层 (Ref. 69278):  3.3   ±0.46 se; based on food items.
回复力 (Ref. 120179):  高度, 族群倍增时间少于 15个月 (tmax=2).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
