Jellyfish
Although most jellyfish live well off the ocean floor and form part of the plankton, a few species are closely associated with the bottom for much of their lives and can be considered benthic. The upside-down jellyfish in the genus "Cassiopea" typically lie on the bottom of shallow lagoons where they sometimes pulsate gently with their umbrella top facing down. The tiny creeping jellyfish "Staurocladia" and "Eleutheria" cannot swim, and "walk" around on seaweed fronds or rocky bottoms on their tentacles. Most hydromedusae and scyphomedusae that live in coastal habitats find themselves on the bottom periodically, where they may stop swimming for a while, and certain box jellyfish species also rest on the sea bed in shallow water. Even some deep-sea species of hydromedusae and scyphomedusae are usually collected on or near the bottom. All of the stauromedusae are found attached to either seaweed or rocky or other firm material on the bottom.
Ornate box turtle
The home range of the ornate box turtle covers a large area of the Midwest, from Wisconsin to the Gulf of Mexico and from Louisiana to Colorado. It was first discovered in Nebraska in 1795, where "vast numbers" were found. The turtle is usually found in grasslands and on land rather than in water; they have been found in all habitat types of the Great Plains except aquatic, though most references indicate they prefer open grass or prairie lands. Several studies indicate that the ornate box turtle needs three specific types of microhabitats in order to survive:
Water is important for this turtle to regulate body temperature in hot weather and to replace body water after hibernation, but they do not spend large amounts of time in flowing or standing water.
