6-month-old platypus found in Australia's Royal National Park after successful reintroduction effort.

Researchers have found a six-month-old juvenile platypus in Australia's Royal National Park, marking the first known birth of a platypus in the park in over 50 years. Ten platypuses were reintroduced into the park in May as part of a conservation project. The discovery of the young platypus indicates that the reintroduction effort has been successful, with the animals not only surviving but also breeding in their new habitat.
