| Thomas’ Ichthyomyine, a water mouse, is sometimes found in very small forest streams in the highlands of southern Mexico, Guatemala, and El Salvador. Its diet apparently includes insects, insect larvae, birds, salamanders, and even other mammals. Like other water mice, its nostrils open facing backward, towards its ears, behind flaplike valves. It has small eyes and ears and webbing between its hind toes, all adaptations to a semiaquatic life. Little is known about reproduction in this animal; however, a pregnant female was carrying just one embryo.
