An unusual sight has brightened a city's harbour when a gorilla flotilla launched a summer art spectacle.
A selection of colourful, life-size gorilla sculptures sailed into Bristol in spectacular style aboard three boats to officially launch Wow! Gorillas, a mass public art trail across the city's streets.
Sixty unique Wow! Gorillas sculptures are appearing to celebrate Bristol Zoo's 175th birthday year.
Dr Bryan Carroll, director of Bristol Zoo, said: "This summer is Bristol Zoo's 175th birthday and we wanted to celebrate this milestone with the whole of Bristol and beyond.
"We hope these fantastic gorillas will unite residents, visitors, schools, artists and businesses in a city-wide celebration of the zoo's big birthday.
"They are absolutely brilliant to look at and a lot of hard work has gone into producing them.
"The support for this wonderful project has been amazing and we hope the people of Bristol will enjoy them and be proud of what the city has come together to create."
The public will be able to see the gorillas at some of Bristol's many famous landmarks for 10 weeks.
Once the exhibition has come to an end, the sculptures will be sold at auction in September to raise money for Bristol Zoo's gorilla conservation projects and Wallace and Gromit's Grand Appeal, which raises funds for the Bristol Royal Hospital for Children.
