Black-legged dart frog

The black-legged dart frog ("Phyllobates bicolor"), also known as the bicolored dart frog or Neari in Choco, is the second most toxic of the wild poison dart frogs. It lives in Colombia. Scientists have seen it between 400 and 1500 meters above sea level.
Appearance.
The adult male frog is 32.1-39.5 mm long from nose to rear end and the adult female frog is 35.7-42.7 mm. It has large disks on its toes for climbing. Young frogs have stripes on their sides. In some groups of this frog, the stripes go away when the frog is an adult. In other places, the adult frogs keep their stripes.
Poison.
Human beings who live where the frog lives have used the frog to poison arrows. The human can touch the arrow to the frog's back without killing it. Or the human can kill and heat the frog's body.
The poison in the frog's skin is a chemical called batrachotoxin. The frog gets the poison from the ants and other insects that it eats. So frogs kept as pets do not have poison.
Threats.
There are fewer of these frogs than there were. Scientisis think this could be because human beings change the places where the frog lives. Humans turn the forests into forms and take the trees for lumber. Human beings also catch these frogs to sell as pets.
