Marine organisms are living creatures that inhabit oceans, seas, and other saltwater environments. They range from tiny plankton to massive whales, showcasing a vast diversity of life forms. These organisms play crucial roles in the ecosystem, contributing to food chains and maintaining the health of marine habitats like coral reefs and kelp forests. Many marine organisms, such as fish, sea turtles, and octopuses, have unique adaptations that help them survive in their underwater world. Some can camouflage themselves to avoid predators, while others have developed special ways to communicate or find food. Understanding these creatures is essential for protecting our oceans and their ecosystems.
