Question

name the different categories of the marine life

Answer 1

How can you visit marine life?

It's easiest to get to the relatively shallow seafloor just offshore. Experienced divers can descend to 130 feet (43 ft), which gives them access to most marinelife. Manned submersibles can descend to the bottom of the deep ocean. Where would you like to go? A coral reef or a hydrothermal vent?

Living Things in the Ocean

Marine organisms range in size from tiny bacteria to the largest known animal, the blue whale. All are adapted for life in salt water. Most are adapted for extreme pressures.

When you think of life in the ocean, do you think of fish? Actually, fish are not the most common life forms in the ocean. Plankton are the most common. Plankton make up one of three major groups of marine life. The other two groups are nekton and benthos (Figure below).
