100 critically-endangered species


This is the Pygmy Three-toed Sloth that lives on a few islands off Panama. Only a few hundred of these beautiful beasties are alive today. Like the Sumatran rhinoceros, Tonkin Snub-nosed Monkey, and Attenborough's Pitcher Plant, the Pygmy Three-toed Sloth is one of the 100 most critically-endangered species, according to a new report from the Zoological Society of London and the International Union for Conservation of Nature. At this week's IUCN World Conservation Congress in Jeju, South Korea, the two organizations published a book and e-book titled "Priceless or Worthless" that profiles these species. "The 100 most threatened species. Are they priceless or worthless?"
