Etymology: Margariscus:Greek, margariskos = pearl (Ref. 45335). Eponymy: These are not eponyms but relate to the meanings of ‘margarita’; pearl and daisy. The dragonfish was so-named due to having a “pearl-colored spot above the maxilla”. (Ref. 128868), visit book page. More on author: Cope.
North America: Atlantic Slope of USA from Hudson River drainage in Vermont and New York, south to Potomac River drainage in Virginia; upper Ohio River drainages in south New York to West Virginia (Ref. 86798); Canada from British Columbia to Newfoundland and Nova Scotia (Ref. 52559), Northwest Territories, and Yukon Territory (Ref. 119194). 北美洲: 在加拿大南部與美國北部從大西洋的岸邊到西北地區南部, 東方的加拿大的英屬哥倫比亞與美國的蒙大納中的大西洋，哈得遜灣，五大湖與密西西比河流域; 南至維吉尼亞，密西根州，威斯康辛州與美國愛荷華州; 在密蘇里河流域上游。

成熟度: Lm9.4 range ? - ? cm Max length : 16.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 86798); common length : 9.3 cm TL 雄魚/尚未辨別雌雄; (Ref. 12193); 最大年齡: 4 年 (Ref. 12193)
Margariscus margarita is almost identical to Margariscus nachtriebi but can be distinguished from this species by having larger scales and usually 50-62 lateral scales (Ref. 86798). Body shape (shape guide): elongated.
Adults inhabit pools of upland creeks and small rivers, and also ponds and lakes. Usually found over sand or gravel (Ref. 86798). They feed on copepods, cladocerans, chironomids, beetles, filamentous algae, and Chara (Ref. 1998). Spawning occurs in spring (Ref. 1998).
Spawning occurs in shallow rivers with moderate current, on sand or gravel. Males maintained territories 20.3 cm wide (at least 1.83 m apart from each other). A ripe female is driven onto the territory. The male places his pectoral fin beneath the female's body anteriorly, and his caudal fin placed over the caudal peduncle of the female. The pair vibrates and the eggs are deposited. Females spawn with different males.北美洲: 在加拿大南部與美國北部從大西洋的岸邊到西北地區南部, 東方的加拿大的英屬哥倫比亞與美國的蒙大納中的大西洋，哈得遜灣，五大湖與密西西比河流域; 南至維吉尼亞，密西根州，威斯康辛州與美國愛荷華州; 在密蘇里河流域上游。
