Downtown Camden traffic came to a halt late Friday morning as a parade of animals wound its way down one side of Elm Street and back up again.

Spotted in the group were an elephant, a panda, a raccoon, a cat and a narwhal, among other animal species, as well as a variety of plants and flowers.

The occasion was the upcoming Earth Day, April 22, which children from Peopleplace Cooperative Preschool and Children’s House Montessori School, both in Camden, celebrated a little early.

In the days leading up to Friday’s parade, the children collaborated on their costumes, which included papier-mâché animal masks and decorated headbands. The children also created stemmed flower bunches, flags and banners to carry along the parade route.

The first all-species parade was held in San Francisco in 1978. In 2000, the All Species Foundation was created with the goal of cataloging every living species on earth within one human generation (25 years).
