Fin whales: A success story © Luis Quinta/Minden Pictures
Today marks the fifth anniversary of World Wildlife Day, the United Nations-backed celebration of all the animals that share our planet. And this is the first year that World Wildlife Day is focusing on marine life. Fin whales, like the one in our photo today, are listed as ‘vulnerable’ on the conservation status rankings. So, they’re threatened by climate change, pollution, shipping, and other concerns, but they’ve bounced back from the brink since the early 1900s, by which time centuries of whaling crews had hunted fin whales to near extinction.
