Nekton. Nekton are the animals that can move by themselves in the ocean waters. Nekton live in all zones of the ocean. However, just like benthos and plankton, most live in the sunlight zone or shallow twilight zone since there is the most sunlight and it is easy to feed on smaller organisms such as krill and minnows.
Oceanic Zones. There are four major oceanic zones where plants and animals live in the ocean. The four major zones are intertidal zone, neritic zone, open ocean zone and benthic zone.These zones contain the largest ecosystem on Earth.nimals found in this zone include the giant squid, deep sea hatchetfish and bioluminescent jellyfish. Benthic zone. The benthic zone includes the entire seafloor. About 200,000 species of plants and animals live here.
