The document provides an overview of various sea life found underwater, including creatures with fins and tails that feed on seaweed or prey, colorful coral reefs and plants on the ocean floor, sea turtles that lay eggs on beaches, schools of fish that swim together, colorful but sometimes poisonous fish like lionfish, giant whales larger than ships, pink krill that swarm in great numbers, glow in the dark plankton and fish, and sea horses where males give birth to about 150 babies that emerge from their stomachs. The concluding message is that the ocean is vast and should be protected from pollution to celebrate its freedom.
