Fish are among the most diverse and widespread animals on Earth, found in nearly every body of water from deep oceans to small freshwater streams. With over 30,000 known species, they vary greatly in size, shape, and behavior. Fish play a vital role in ecosystems, serving as both predators and prey while maintaining the balance of aquatic life. They are also a major food source for humans and other animals, providing essential nutrients and supporting economies through fishing industries. Adaptations such as gills for breathing, scales for protection, and fins for movement make them perfectly suited to aquatic environments. From colorful tropical species to massive deep-sea dwellers, fish display remarkable diversity and resilience. It is clear that fish remain essential not only for ecosystems but also for human culture, food, and survival.
