From Pathfinder Wiki
- Surface film
- The surface film is the top six inches of water on the pond's surface. This habitat is where many types of life exist, including mosquito larvae, air-breathing animals, and insects that can "walk" on the surface by exploiting its surface tension. Life on the surface is not limited to the animal kingdom however. You may also find floating plants and algae there.
- Open water
- fish, turtles, plankton, phytoplankton, crustaceans
- Bottom
- Animals that live in the mud on the bottom of a pond include crayfish, dragonfly nymphs, rotifers, and bacteria. These animals feed on dead organic matter that makes its way to the bottom.
- Shore
- On the shore of a pond you will find many plants. Some of these plants grow on the bank, others grow in the water, and still others grow in both places. Some plants will have roots under the water, but stems, leaves, and flowers above the surface. Others will grow completely under the water.
