Several species of plants in the Buttercup Family are aquatic, growing underwater in lakes and ponds. A few are even amphibious, meaning that a single plant lives partly on sand along a shoreline and partly submerged. Such plants have runners, like a strawberry plant, and grow roots along the runners. The submerged leaves appear quite different from the ones growing in air.
