Aquatic Biomes

An animated science video covering the aquatic biomes.

Includes freshwater biomes and marine biomes.

Summary: The Earth is covered with water. It is called the blue planet because seventy percent of Earth is water. Aquatic biomes are organized into freshwater biomes and marine biomes.

Key points:
Freshwater biomes are areas of water with a low salt content. They can be divided into river and streams, lakes and ponds, and wetlands.

River and streams are freshwater bodies of water that flow in one direction. Rivers and streams can be found everywhere. The start of a river or stream is called the headwaters and the end is called the mouth.

Lakes and ponds are standing bodies of freshwater. They can be as small as a few square yards to hundreds of square miles. Some ponds may even be seasonal. Lakes and ponds have limited biodiversity.

Wetlands are transitional bodies of water between the land and often lakes and streams. They are literally "wetlands."  Two common types of wetlands found in North America include marches that do not have trees and swamps that do contain trees.

Marine biomes have a high salt content. The three major marine biomes include the ocean,estuaries, and coral reefs.

The ocean is divided into five main oceans. These include the Pacific,Atlantic,Indian,Arctic, and the Southern ocean. The ocean is full of life and it varies from forty foot whales down to microscopic plankton.

Coral reefs are formed from coral. These coral consist of both algae and animal polyp. Coral reefs are found in warm shallow waters and have great biodiversity.

Estuaries are bodies of water that have fresh water feeding into them and are also open to the ocean. The are nicknamed the " nurseries of the sea" because they are a safe area to raise young animals.
