This Pendant depicts the fascinating, death-defying Planarian! Planaria are flatworms (order Platyhelminthes) that are common in aquatic and moist terrestrial environments worldwide. Despite their complex internal anatomies, Planarians are able to regrow amputated body parts, and even nearly complete bodies when injured. This amazing capability makes Planarians a perfect model for the study of animal development and regeneration. Comes with an adjustable-length 2mm black leather necklace cord.
