Scientists at the Vancouver Aquarium say critically endangered Panamanian golden frogs have been bred at the facility for the first time in its history.
The breeding program is part of a world-wide effort to preserve the species, which has been almost wiped out over the last decade.
Habitat loss and decimation by a deadly type of fungus are two reasons for the decline, according to Project Golden Frog, which was launched in 1998 to save the dwindling species.
Panamanian golden frogs are known for their bright golden colours and distinct wave used in mating.
The creature, a species of toad, is no larger than seven centimetres and lived almost exclusively in freshwater streams of Panama's high elevation cloud and rain forests.
