Fish News
Fish are a diverse group of aquatic organisms that inhabit both freshwater and marine environments around the world. They range from tiny species like the Paedocypris, which is just a few millimeters long, to massive ones like the whale shark, which can grow up to 60 feet in length. Fish are characterized by their vertebrate nature, gills which they use for breathing underwater, and, typically, scales covering their bodies. There are over 33,000 known species of fish, making them the most diverse group of vertebrates. Fish play essential roles in aquatic ecosystems as both predators and prey, contributing to the balance of these environments. They are of significant economic importance to humans, providing a major source of protein, recreational opportunities through fishing, and livelihoods in fishing industries. Additionally, many species are kept in aquariums for decorative and educational purposes.
