Wondiwoi tree kangaroo

While the Wondiwoi tree kangaroo was thought to be extinct, the first-ever photographic evidence of its existence was taken in July of 2018 by British naturalist Michael Smith. The animal was discovered in a largely unexplored area of the Wondiwoi ranges of New Guinea. To this day, there are thought to be approximately only 50 living Wondiwoi tree kangaroos, due to their limited habitat.
