gam·bu·sia

 (găm-byo͞o′zhə)
n.
Any of various small live-bearing fishes of the genus Gambusia of the Americas, which are popular in home aquariums and have become widely naturalized because of their use for mosquito control.

[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.]

All surviving Big Bend gambusias have descended from these three fish.
One of just two existing populations of the Big Bend gambusia (Gambusia gaigei) was lost when the spring went dry.
With a precariously low population, the gambusia's chances for survival were grim and extinction seemed inevitable.
