Aplastodiscus albosignatus

Lutz's tree frog or the bocaina tree frog ("Aplastodiscus albosignatus") is a frog. It lives in Brazil.
The adult frog is 40 – 51 mm long from nose to rear end. The skin of the frog's back is green in color. Its bones and muscles are green too.
The tadpoles live at the bottom of the body of water.
There are fewer of this frog than there were. Human beings cut down the forests where the frogs live. They take trees for wood to build things and to make towns.
