Lehmann’s Poison Frog, Dendrobates lehmanni

Lehmann’s Poison Frog (Dendrobates lehmanni) known also as the Red-banded Poison Frog, is a species of frog belonging to the Dendrobatidae family. It’s native to Colombia. Its natural habitats are tropical and subtropical moist lowland forests and subtropical or tropical moist montane forests. It is threatened by habitat loss and was named after Colombian biologist Federico Carlos Lehmann.

This frog is listed as Critically Endangered on the IUCN Red List of Threatened Species.

Both sexes reach 31 to 36 millimeters in length. The skin is smooth and the first digit is a little shorter than the second digit. There are three color morphs that exist in this species. The color morphs are red, orange, and yellow against a dark brown or black background. The majority of the frog is dark but it’s encircled by two brightly colored bands; one behind the head and the other one around the hump of the back. The pattern continues onto the belly. Each individual frog displays different patterns. The arms and legs also have colored bands. The toes in the males are silver at the tips.

It eats mostly insects and is active during the day. Immediately after the rainy season, the males find appropriate places to store eggs and attract the females by a series of calls. Once the female chooses a male, she will deposit a few large eggs about 1.2 meters above the floor of the forest on leaves within the area that the male has chosen. The male fertilizes the eggs and looks after them to insure their survival. He periodically rotates the eggs to insure they receive the right amount of oxygen. The tadpoles are fed unfertilized eggs from the female. Common areas for tadpoles to mature include bromeliads, hollow trees, and bamboo stalks. It takes two to three months for tadpoles to develop into adults.
