A set of images showing a male Ranitomeya benedicta carrying 3 tadpoles. He sat in the bromeliad for several minutes, but I don't think any of the tadpoles went into the water, unfortunately I couldn't count them again as he looked around and then travelled to another bromeliad and went out of my view.
@birdsandbats Paignton has about a dozen species of poison dart frogs and mantellas on show now. I believe that most of their dart frogs came from Understory Enterprises. This is an ethical company, collecting limited numbers of animals and breeding them in captivity for controlled export and for reintroduction if required.
@birdsandbats It was not discovered relatively recently, it's discribed relatively recently. Prior to this, it was considered a colour morph of Dendrobates fantasticus. I've seen D. benedictus even in a pet shop... I don't know how it works for amphibians, but in fishes many recently discovered freshwater species (overall small catfishes and cyprinids) are very easily found in any aquarium shops and even many are easy to find years before their description... then known by a number or a collecting locality until they get a scientific name.
