What adaptations have formed in living organisms of swamps?

Since there is a lot of water and little oxygen for plants in swamps, plants that grow in such conditions have the following adaptations: such plants evaporate otherwise; large leaf surface; the use of oxygen directly from water, and oxygen along with air enters through large stomata; the air from the leaves through the air chambers is able to penetrate to the roots of plants, they have a poorly developed root system. Animals have the following adaptations: skin respiration; mucus-covered skin; long legs; webbing for swimming between the toes.
