Whale sharks – illegally captured for sale to ocean theme parks in China – are released from sea pens, Ambon, Indonesia on May 29, 2016. Agents of the Ministry of Fisheries and Maritime Affairs found two whale sharks, each about 14 feet long, being held in submerged pens. Even fully grown, the sharks are harmless, slow-moving fish, typically swimming with mouths agape to filter-feed on plankton. Divers entered the pens and guided the sharks, which had been held for three months, back to freedom. (Photo by Paul Hilton for WCS)

Fluorescent paint makes the antlers of a reindeer shine, in this photo dated February 15, 2014, after Finnish herders painted the animal in an attempt at halting the thousands of road deaths of the roaming caribou in Rovaniemi, the wilds of Finland's Lapland. This novel attempt to reduce the annual 4,000 reindeer road deaths was not successful, so in a pilot project announced Wednesday June 8, 2016, drivers of heavy transport vehicles are being offered a reindeer warning app for their mobile devices, to warn them of nearby reindeer. If successful, The Reindeer Herders Association hope the app will be available for download on all smart phones later in 2016. (Photo by Anne Ollila/Lehtikuva via AP Photo)

In this photo taken on April 28, 2016, a koala who goes by the name of Ocean Summer who is blind from brain damage resides at the Koala Hospital in Port Macquarie. The outlook for koala populations on Australia's east coast is dire as habitat loss, dog attacks, car strikes, climate change and disease take their toll. While there were believed to be more than 10 million koalas before British settlers arrived in 1788, a 2012 national count placed their total numbers at around 330,000, though their existence in treetops makes accurate assessment difficult.
