Telmatobius laticeps

The Tucuman water frog (Telmatobius laticeps) is a frog. It lives in Argentina.^[2][3][1]

Between 1949 and 1989, scientists used this frog in laboratories. They would use this frog to study the way chemicals in the body work, allergies, the way very young things grow inside eggs or their mothers, how to make pictures of big pieces of DNA, and other things. Scientists do not use this frog in laboratories now.^[1]

This frog spends almost all its time in the water. It lives in streams near bogs, grassy places, and places with some trees but not many. Scientists saw this frog between 1900 and 3100 meters above sea level.^[1]

The female frog lays between 80 and 500 eggs at a time.^[1]

Scientists say this frog is in very big danger of dying out. They think there are no more than 49 adults alive at any time now. Fish from other parts of the world, for example trout, may have killed these frogs. People also change the places where the frog lives to make towns and farms and other things that people need, for example cables for electricity. People also move streams to make canals for boats. Scientists also found what looks like chytridiomycosis in the frog's tadpoles, so they think the disease may kill the frogs.^[1]
