About Peces
Fish are aquatic vertebrates that typically breathe through gills and move using fins. They are the most diverse group of vertebrates on Earth, with over 34,000 known species.
From the tiny dwarf goby to the massive whale shark, fish have adapted to nearly every aquatic habitat on Earth. They can be found in freshwater lakes and rivers, coral reefs, the deep sea, and even in the frigid waters of the polar regions.
