Osteichthyes

Osteichthyes are a class of bony fishes, meaning they have a skeletal system made of bone rather than cartilage. This makes them a crucial evolutionary link between fish and other land animals. Osteichthyes make up the majority of fish species in our oceans and rivers, such as trout, tuna, and salmon. They are important for commercial and sport fishing, providing us with essential food sources, as well as recreational activities for people around the world. Osteichthyes are also essential to the health of aquatic ecosystems, not only providing a food source for other animals, but also helping to keep the water clean by consuming algae and other organic matter.
