Alkali Flies in Mono Lake, California
The alkali fly Ephydra hians can crawl into water, and dive up to eight meters deep. When they resurface, they are as dry as Sahara sand. Biologists of the California Institute of Technology in Pasadena found out that these flies are covered in hairs that are coated with a special wax. This makes it possible that an air bubble forms around the body, not only to keep them dry but also to provide oxygen for breathing under water. The flies live in Mono Lake in California and are an important food source for migrating birds.
