aquatic animals

Aquatic animals are creatures that live in water, including oceans, rivers, lakes, and ponds. They can be broadly categorized into two groups: fish and non-fish. Fish have gills for breathing underwater, scales, and fins for swimming, while non-fish species include amphibians, mammals (like whales and dolphins), crustaceans (like crabs and shrimp), and mollusks (like octopuses and clams). These animals play crucial roles in ecosystems, contributing to food webs and maintaining aquatic health. They have adapted to various aquatic environments, demonstrating remarkable diversity in form, behavior, and habitat.
