Things were even wilder that usual at London Zoo last week as a mob of streakers bared all in support of Sumatran tigers. 300 naked runners - representing the number Sumatran tigers left in the wild - ran through the iconic venue as part of a unique fundraising event.
Taking place after the Zoo had closed to daytime visitors, the Streak for Tigers ran past some cheeky monkeys and bearded pigs as well as friends and family who cheered them on to the finish line. The fearless fundraisers raised over £65,000 for Zoological Society of London's (ZSL) work with the critically endangered species in Sumatra.
ZSL is already working in Indonesia and Russia and supporting projects in Bangladesh to lobby policy makers, create wildlife corridors, patrol tiger habitats, carry out monitoring and work with local communities to reduce tigers' conflict with humans.
