What are the characteristics of bony fish?

Bony fish, also known as Osteichthyes, are a diverse group of aquatic animals that possess several characteristic features. Firstly, they have a bony skeleton, which differentiates them from cartilaginous fish like sharks and rays. Their bodies are covered with scales, providing protection and aiding in their movement through the water. Bony fish have gills, allowing them to extract oxygen from the water, and most species have a swim bladder, an air-filled sac that helps control their buoyancy. They also have paired fins, which aid in maneuvering and stabilization. Bony fish reproduce by laying eggs, and their diets can vary widely, with some species feeding on plants, others on small invertebrates, and some being predatory. Overall, the characteristics of bony fish reflect their adaptation to the aquatic environment.
