Box turtle with trail laying device

Detailed Description

Box turtle with trail laying device designed by Dr. Lucille Stickel in the 1940s. To track turtle movements, Dr. Stickel improved on an earlier trailer design described in 1927 and noted, “Details of travels can be followed for weeks or months by attaching thread- laying devices to their carapaces. Their normal activities are not detectably altered by the attachment of these trailers, or by handling and marking.” Credit: Stickel 1950.
