Although all dendrobatids are at least somewhat toxic in the wild, levels of toxicity vary considerably from one species to the next, and from one population to another.

Chile Darwin's frog
The Chile Darwin's frog was fairly regularly seen until around 1978,since when it seems to have disappeared, and the species may now be extinct. This species, which lives in the leaf litter on the forestf loor, has an unusual method of parental care; the male takes the fertilised eggs from the nest into his vocal sac where they hatch into tadpoles after approximately eight days. When he starts to feel the newly hatched tadpoles wriggling, the male carries them to a stream where he expels the young. Here they complete metamorphosis.(Link | Photo)
