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.

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.
