There are about 30,000 known species of animals in the sea. Each of them has its own method of activity. Sea cucumbers crawl by stretching and contracting their muscles and can only move forward four meters per hour. There is a fish with a shuttle-like body that can swim dozens of kilometers per hour. Squids and octopuses can suddenly spray water forward and use the reverse thrust of the water to quickly retreat. There are also some shellfish that do not move on their own and can travel long distances for free under the ship.

There are mountains, canyons, forests and grasslands under the sea. Plants come in many colors, including brown, purple, and red. The smallest single-celled algae can only be seen clearly with a microscope. The largest seaweed is two to three hundred meters long, making it the longest living thing on earth.

There are rich deposits of coal, iron, oil and natural gas on the sea floor, as well as rare metals found in small amounts on land.
