The SE1-based League Against Cruel Sports has presented European Union Environment Commissioner Margot Wallstrom with a petition urging legislation banning the importation of animal trophy parts.
Many of the animal species are listed under the Convention on International Trade in Endangered Species as endangered or threatened.
The petition handover by League Vice-President Robert Evans MEP and Head of Public Affairs Mike Hobday took place at the European Parliament in Strasbourg.
Robert Evans said: "Trophy hunting is the retail slaughter of thousands of beautiful endangered animals in the name of sport. It is an abhorrent practice. I will continue to press hard within the European parliament to bring an end to this modern day barbarism."
Mike Hobday said: "The list of trophy parts from endangered animals which have been imported into the EU since 1996 includes 2,623 highly at risk leopards, more than 9,000 bears, nearly 4,000 elephants and thousands of zebras, lions and hippopotami.
"Everyone who has signed this petition believes it is unacceptable that tens of thousands of animals have been killed by EU hunters."
