Blue-legged mantella description
With a greenish-yellow back contrasting with dark blue hind legs and black sides, the blue-legged mantella is a popular frog in the pet trade. Males are a little smaller than females and have an obvious horseshoe-shaped blue spot on the lower throat. Both sexes have a light stripe along the upper lip. Colours can vary between individuals, but the more highly contrasting individuals are most likely to be collected for the pet trade (1).Top
Blue-legged mantella biology
Active during the first hours after dawn, the blue-legged mantella is most easily observed from October to December during the rainfalls that stimulate egg-laying. Males call continuously to attract females, who then emerge from their refuges to lay two to six clutches of over 35 eggs each (2) (3).Top

Blue-legged mantella threats
Several thousand blue-legged mantellas are thought to be collected every year from some regions in the Isalo Massif(3). Aside from over-collection, the extremely small range of these critically endangered frogs is threatened with habitat loss as a result of grazing, fires and sapphire mining operations (1).Top
Blue-legged mantella conservation
Listing on Appendix II of the Convention on International Trade in Endangered Species provides the blue-legged mantella with some protection. It requires that an export licence is obtained for any trade in this species. A trade quota to prevent over-exploitation of this frog is crucial to its survival, as even the protection offered by the Isalo National Park has not prevented the capture of the blue-legged mantella (1). Anyhow, recent research showed that the species is still locally abundant (5).Top
