A wildlife park in the UK has successfully bred "rare" giant Mexican leaf frogs - for the first time in its history.
The Cotswold Wildlife Park has become the only zoological collection in the world to successfully breed the species in the last year.
The amazing feat saw keepers organise the "highly special" conditions in which the giant Mexican leaf frogs were able to breed.
The species originated in the sub-tropical area of Mexico and full-grown adults will get to only 10 centimetres long, Gloucestershire Live reports.
They are a nocturnal amphibian that usually eats insects. In the wild, the breeding takes place near water sources such as ponds and swamps and once the spawn hatches they fall into the water.
The wildlife park has dubbed one frog "Bowie" due to its striking eyes and another "Grumpy" for obvious reasons.
Cotswold Wildlife Park said: "For the first time in the Park’s history, the Reptile Team has successfully bred Giant Mexican Leaf Frogs.
"In the wild, this unusual species is found only in the sub-tropical forests of Mexico and requires highly specialised conditions to breed.
"Cotswold Wildlife Park is the only zoological collection in the world to have successfully bred Mexican Leaf Frogs in the last twelve months and has become only the second collection in history to have achieved success breeding these rare amphibians."
Elsewhere, a rare penguin chick has hatched at Edinburgh Zoo.
The endangered Northern rockhopper is the very first chick of penguin breeding season, born to parents Pinny and Bruce.
As well as being part of the European breeding programme for Northern rockhopper penguins, the Royal Zoological Society of Scotland has helped safeguard the species in the wild, studying breeding populations on remote islands in the Atlantic and Indian Oceans.
Michael Livingstone, senior keeper at Edinburgh Zoo, said, "Northern rockhopper penguins are endangered due to climate change, changes in marine ecosystems and overfishing, so it is really exciting to welcome a new chick.
"The first 30 days are critical for their development, so we will be keeping a close eye on the youngster at this sensitive time.
"Last year we welcomed two Northern rockhopper chicks, Sandy and Frankie, who have settled into the colony well.
"Every visit to Edinburgh Zoo helps care for all our amazing animals, like our penguins, and helps protect threatened species at home in Scotland and around the world."
