Limosa Harlequin Toad (Atelopus limosus), is an endangered species of toad in the Bufonidae family. It is endemic to Panama. Its natural habitats are stream banks in subtropical or tropical moist lowland forests and rivers of the Chagres watershed in central Panama.Little is known of their diet in the wild, but it is presumably similar to that of other Atelopus species that forage on beetles, ants, flies and mites.
Atelopus limosus is threatened by chytridiomycosis and habitat loss. Atelopus species have been rapidly declining throughout their range. 75% of all known species from highland sites above 1000 metres have disappeared, while 58% of lowland species have declined and 38% have disappeared.
