Name 3 types of science that are used in marine

The phytoplankton (left) and zooplankton (right) shown here have been magnified. Otherwise, they would be too small for you to see.

Nekton are living things that swim through the water (Figure below). They may live at any depth, in the photic or aphotic zone. Most nekton are fish, although some are mammals. Fish have fins and streamlined bodies to help them swim. Fish also have gills to take oxygen from the water.

Nekton swim through ocean water.

Benthos are living organisms on the ocean floor. Many benthic organisms attach themselves torocks and stay in one place. This protects them from crashing waves and other water movements. Some benthic organisms burrow into sediments for food or protection. Benthic animals may crawl over the ocean floor. Examples of benthos include clams and worms. Pictured below are two other examples (Figure below).

These animals live on the ocean floor.

Some benthos live near vents on the deep ocean floor. Tubeworms are an example (Figurebelow). Scalding hot water pours out of the vents. The hot water contains chemicals that some specialized bacteria can use to make food. Tubeworms have the bacteria living inside them. The bacteria get protection and the tubeworms get some of the food.

Tubeworms live near hot water vents on the deep ocean floor.

lizards have adapted to life in the desert. some desert lizards have toes with spiny scales to them run across the sand without sinking. some use the sand to hide from predators, or to search for small animals that they prey upon.
