Don't be fooled by the beautiful images of majestic animals on these new jigsaw puzzles—there's a more sobering message baked into them.

Created by World Wildlife Fund Canada, the new product highlights the fact that these particular animals are under threat of extinction, and each one of the limited edition "Endangered Pieces" puzzles contains only as many pieces as there are animals left in the wild.

The giant panda puzzle is the largest one, containing 1,864 pieces (thanks to WW's conservation efforts). The Sumatran tiger puzzle is 400 pieces, the pygmy three-toed sloth is 79 pieces and the Southern Resident killer whale is the smallest offering with just 73 pieces.

The campaign was conceived to mark National Panda Day today (March 16) by agency AKQA together with Copenhagen-based image studio Kühl & Han on visuals and films, and Jocelin Carmes on the artwork illustrations.

The puzzles are available globally to order online, priced between CAD $30-$40. 

"Proceeds from Endangered Pieces will advance our ambitious plans to restore nature and safeguard wildlife," said Mark Charles, WWF-Canada's vice president of marketing, in a statement. “We are working hard to ensure that as this initiative grows, the number of pieces in each puzzle will grow as well.”
