Photographer Tim Flach’s latest book Endangered, with text by zoologist Jonathan Baillie, offers a powerful visual record of threatened animals and ecosystems facing the harshest of challenges.
Common hippopotamus, Hippopotamus amphibius.
IUCN Red List status: Vulnerable.
In 2003, surveys showed that the number of hippos had dropped by 95% during eight years of civil war in the Democratic Republic of the Congo.
Hippos are hunted for bushmeat but have become the focus of poachers interested in their ivory canines following the 1989 ban on trading elephant ivory.
International trade out of several African countries is restricted, but the law is not yet enforced on the ground.
Today, African elephants outnumber hippos four to one.
