Flexi Says: Hydras look like tiny sea anemones that are connected to a tube-like body. At the end of the tube is a mouth rimmed with several long tentacles. A sticky secretion at the “foot” end enables hydras to cling to a surface. Hydras can glide slowly on their foot, or they can bend over and turn slow-motion somersaults. Hydra bodies are only two cell layers thick. Most hydras are only 1/2 to 2 inches long when stretched out. Hydra colors vary with species. They can be gray, brown, tan, cream-colored, green, orange, whitish, pinkish and even “clear.”
