Insuetophrynus acarpicus

Barrio's frog  (Insuetophrynus acarpicus) is a frog.  It is the only frog in the group Insuetophrynus.  It lives in Chile.

Body
Adult male frogs are 40.5 – 56.3 mm long from nose to rear end and adult female frogs are 35.2 to 50.0 mm long. Right after they become frogs, male frogs are 19.1 – 28.1 mm long and new female frogs are 20.8 – 26.5 mm long. Adult frogs are green-gray in color. Young frogs have more green than adults. The back legs have dark stripes on them. They have short, thick front legs and long, thin back legs.

Home
This frog spends time in water even though it does not swim well. It lives in small streams in forests. It stays in the water during the day and goes on land at night. Scientists saw this frog between 50 and 1100 meters above sea level.

Scientists saw the frog in one protected place: Alerce Costero National Park.

Young
The tadpoles can grow as long as 61.00 mm with the tail.  The skin of the tadpole's back is green-brown with some patterns. The tail and fins have light brown spots made out of dark cells and guanophores. The skin of the belly is clear. A person can see the tadpole's guts.

Danger
Scientists from the IUCN say this frog is in danger of dying out. People cut down too many trees at the same time to get wood to build with, to make pine tree farms and places for cows to eat grass.  People also start fires. Bad chemicals in the water can also hurt this frog, for example, from the soap that people use when they wash their bodies in the streams.
