Water: Ocean Life

The video explores the diversity of ocean organisms, starting with sea anemones, which are animals despite their plant-like appearance. It categorizes ocean life into benthic organisms, plankton, and nekton. Benthic organisms like rock crabs and starfish live on the ocean floor. Plankton, including jellyfish and zooplankton, float and are carried by currents. Phytoplankton, a type of plankton, are crucial for the ocean's food chain and oxygen supply. Nekton, such as fish and sharks, are free-swimming organisms.
