North America: Atlantic Slope from St. Lawrence River drainage in Quebec, Canada to upper Roanoke River in North Carolina, USA (absent in most of New England; present in Connecticut River, Vermont based on single record); Lake Ontario drainage in Ontario, Canada and New York, USA. Also present in upper New River drainage in West Virginia and Virginia, USA where may be based on introduction.

简单描述 检索表 | 型态特徵 | 形态测量图

Exoglossum maxillingua resembles tonguetied minnow, E. laurae, but can be distinguished by the presence of much larger fleshy lobe on each side of lower jaw, well separated from central bony plate and followed by another fleshy lobe on underside of head, and by absence of barbel near corner of mouth (Ref. 86798).

生物学特性     字汇 (例如 epibenthic)

Inhabits rocky pools and runs of creeks and small to medium rivers. Usually found in quiet water near boulders. Males construct large circular or rectangular nests by piling pebbles carried in the mouth (Ref. 5723, 86798). Feeds on insects and mollusks (Ref. 54729).

栖息于小溪及小型到中型河川的多岩石的水池与小支流。 在大圆石附近的通常发现于静止的水域。 繁殖期的雄性建立大而圆形或矩形的巢用嘴巴堆砌小圆石。 (参考文献 5723) 吃昆虫与软件动物。 (参考文献 54729)

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00376 - 0.01926), b=3.06 (2.86 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
营养阶层 (Ref. 69278):  3.0   ±0.33 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).
