The Lehmann's poison frog or red-banded poison frog (Oophaga lehmanni) is a species of frog in the Dendrobatidae family. It is endemic to a small part of western Colombia. Its natural habitats are submontane tropical rainforests. It is threatened by habitat loss and collection for the pet trade, and the IUCN lists it as being "critically endangered". It was named after Colombian conservation biologist Federico Carlos Lehmann.

Description[]

Lehmann's poison frog has a smooth skin and exhibits aposematic colouration, which warns predators that it is inedible. There are red, orange and yellow morphs of this frog. The background colour is black or dark brown which contrasts with the two bright, broad bands of colour round the body and further coloured bands on the limbs. The first toe is shorter than the second and the toes of males have silver tips. This frog grows to a snout-to-vent length of 31 to 36 mm (1.2 to 1.4 in).

It is very similar in appearance to the harlequin poison frog (Oophaga histrionicus), a species with which it can hybridise, and there is ongoing debate as to whether it is in fact a separate species. There are distinct differences in the calls of the males between northern and southern populations.

Distribution[]

Lehmann's poison frog is endemic to Colombia where it is found in tropical forests in the drainage of the Anchicayá River to the west of Dagua in Valle del Cauca Department, as well as in one locality in Chocó Department, all on the slopes of the Cordillera Occidental. Its altitudinal range is 600–1,200 m (1,969–3,937 ft). There are several separate populations and the total area of occupancy is less than 10 km² (3.9 sq mi).

Biology[]

Lehmann's poison frog is diurnal and primarily feeds on small insects. It is found on the forest floor and in low vegetation. Breeding takes place at the end of the rainy season. The male chooses a suitable location and calls repeatedly to attract a female. She deposits a small number of large eggs on leaves up to 120 cm (4 ft) above the forest floor where the male fertilises them. He keeps them moist and rotates them occasionally and after two to four weeks he carries them on his back and deposits them singly in small temporary water pools in such places as hollows in trees, water-filled bromeliad rosettes and bamboo stalks. Here the tadpoles develop and the female periodically deposits unfertilised eggs in the water on which they feed. If there are several tadpoles in any water body, cannibalism may occur.

In the wild, Lehmann's poison frog is toxic, but in captivity it loses its toxicity because this is derived from its diet.

Status[]

Lehmann's poison frog is found in a very small area of Colombia. It is present in the Parque Nacional Natural Farallones de Cali and is common in parts of its tiny range but because of the degradation of its habitat for timber extraction and illegal agriculture it is considered by the IUCN to be "critically endangered". Despite being a protected species and listed in Appendix II of CITES, it is sometimes exported as part of the international pet trade.
