Hundreds of people have gone ape on London's streets as they took part in an annual run to raise money. More than 600 people dressed in gorilla suits for the spectacle.
Eager participants ran, or in many cases walked, the 7 kilometer race around central London on Saturday.
Organizers hope the event will raise up to 200-thousand pounds for their work to save the great gorillas in Africa.
According to the Gorilla Organization, as many people participated in the run as there are mountain gorillas left in the wild.
