This undated photo provided by the California Department of Fish and Wildlife shows a Paiute cutthroat trout. For the first time in nearly a century, the California trout species will swim in a mountain creek that is its native habitat, marking a major milestone that conservationists hope will lead to a thriving population and removal of its threatened status. About 30 Paiute cutthroat trout will be plucked Wednesday, Sept. 18, 2019 from Coyote Valley Creek and hauled in cans strapped to pack mules about two miles (3.2 kilometers) to be dumped back into a stretch Silver King Creek in Alpine County's Long Valley, where the shimmering species glided through the cold water for thousands of years.

This undated photo made available by The Pew Charitable Trusts shows the mako shark swimming in the Atlantic Ocean off Rhode Island. Countries have agreed to protect more than a dozen shark species at risk of extinction, in a move aimed at conserving some of the ocean’s most awe-inspiring creatures who have themselves become prey to commercial fishing and the Chinese appetite for shark fin soup. Three proposals covering the international trade of 18 types of mako sharks, wedgefishes and guitarfishes each passed with a needed two-thirds majority in a committee of the World Wildlife Conference known as CITES on Sunday Aug. 25, 2019.
