Living Treasure
Photograph by Wes Skiles
Descending to where no light penetrates—one hundred feet (30 meters) deep into a cenote—expedition biologist Tom Iliffe of Texas A&M University captures an isopod, a type of crustacean, in a specimen bottle. Iliffe studies stygofauna, small, eyeless, colorless animals that survive in the submerged cave systems of the Yucatán. Even deeper, where divers cannot go, living fossils swim in oxygen-depleted waters below the halocline, the boundary layer where lighter fresh water gives way to heavier salt water.
