[New Latin Gambusia, genus name, coined (perhaps in reference to their small size) in 1851 by Cuban zoologist Felipe Poey y Aloy from Cuban Spanish colloquial gambusino, nothing (as in pescar gambusinos, to go on a snipe hunt, literally "to fish for gambusinos"), variant of Spanish gamusino, imaginary creature that children or naive persons are sent to hunt as a practical joke, object of a snipe hunt; perhaps akin to Old French gabuser, to dupe, from gab, mockery, jeering, probably from Old Norse gabb; akin to gabba, to scoff; see gab.]
