Anableps

Genus of the Cyprinodontida, or Mud Minnow, largest of the family, attaining a length of a foot. They swim at the surface, as do the Top Minnows, the upper half of each eye out of water. A horizontal partition divides each eye into IMG:content-0164.jpg:[graphic][merged small] two parts, one adapted for vision in air, the other in water. These fishes resemble some of the other Mud Minnows ( e.g. Gambusia ) in bringing forth their young at an advanced stage of development. They are viviparous, carnivorous, and inhabit rivers of tropical parts of N. and S. America.
