Fish are a diverse group of aquatic vertebrates that inhabit nearly every body of water on Earth, from high mountain streams to the deepest ocean trenches. They range from tiny, translucent species to massive predators like sharks and tuna, and they play vital roles in ecosystems as both predators and prey. Fish are also a key focus in fields like evolutionary biology, marine ecology, and environmental science, offering insights into everything from climate change impacts on ocean life to the origins of vertebrate development. Their biology, behavior, and interactions with changing environments continue to be active areas of scientific research.
