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.
北美洲: 從在加拿大魁北克的聖勞倫斯河流域到北卡羅萊那州的 Roanoke 河上游的大西洋斜坡; 在加拿大安大略省與美國的紐約州的安大略湖流域。 也在新河上游流域在西維吉尼亞與美國維吉尼亞, 在那裡它相信已經被引入。

Max length : 16.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 86798); common length : 10.8 cm TL 雄鱼/尚未辨别雌雄; (Ref. 12193); 最大年龄: 2.00 年 (Ref. 12193)
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).
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)
