    About Harlequin frogs

    • They are typically small to medium-bodied and many of them have bright and contrasting warning colours advertising potent skin toxins.
    •  They are typically diurnal and many of them occur in the vicinity of streams all year long, while others are found inside the forest 
    • They  occur in a diverse array of habitats, from tropical wet forests along the Pacific coast and the Amazon basin to the montane regions and paramos of the Andes
    • They are particularly sensitive to habitat modification, environmental changes, and infectious diseases, potentially making them important sentinel species in the terrestrial and freshwater ecosystems where they occur.
    •  Their presence is an indicator of water quality and healthy ecosystems, and their demise might be an early warning to humans of critical environmental conditions
