Galapagos Tortoise in Duckweed This Galapagos tortoise has high-protein, fast growing duckweed on its face. The ridges on his shell have worn down and are getting polished with age. The pattern of shell ridges is as unique as a fingerprint. The family of duckweeds (Lemnaceae) contain the smallest flowering plants in the world. These plants grow floating in still or slow-moving fresh water around the globe. Rancho Permiso, Santa Cruz Island.
