Pond life - animals & plants

The kinds and numbers of living things found in the still water of lakes and ponds vary greatly. Ponds in clay or river deposits are often rich in life. Rushes and flowers grow around them. The common reed and the reed-mace may grow at the water's edge, often extending into the water. Truly aquatic plants may be rooted with floating leaves, such as water lilies. Others have submerged leaves, such as Canadian pond-weed. Some, including water crowfoot, have both types of leaf. Free-floating plants, which may cover the surface of small ponds, include duckweed and frogbit. Minute floating plants called plankton (see Plankton facts) also flourish. Plants provide food and shelter for animals and also oxygen which dissolves in the water.

Some examples of plant and animal pond life, pond grass

Each part of a pond life animals and plants has its characteristic inhabitants. The surface of the water forms a skin and itself supports some tiny animals. Pond-skaters and whirly-gig beetles are often found skimming across the surface.

Small animals, such as Hydra and water-fleas, get oxygen by simple diffusion from the water. Fishes, such as sticklebacks, have gills which absorb oxygen directly from the water. Such animals can only survive when there is sufficient oxygen in the water. Many animals breathe air and surface periodically. Such animals include water-beetles, water-bugs, some fly larvae, pond-snails and mammals, such as beavers and otters.

Methods used by various water insects to obtain oxygen from the surface of ponds and pond grass

Possibly the most numerous creatures found in a good pond (apart from microscopic protozoans) will be tiny crustaceans, such as Cyclops and Daphnia. The water-boatman, which may attack fish, is often found. The fiercest pond insect is possibly the green and brown great diving beetle, which will attack fish.

Samples taken from weedy areas may contain hydra attached to the plants and numerous water-snails. Caddis larvae and water spiders may also be found. Water-snails breathe air at the surface. The mud at the bottom of a pond often contains snails, worms, leeches and freshwater mussels. Freshwater mussels extract both food and oxygen from the water and keep artificial ponds clear.
