Bony Fish
Bony Fish Overview: Complete Guide to Types, Uses, Characteristics, and Global Importance
Introduction
Bony fish, scientifically known as Osteichthyes, represent the largest and most diverse group of fish on Earth. They make up more than 95% of all fish species, with over 30,000 known types. These fish are called ‘’Bony’’ because their skeletons are made of cartilage. Bony fish inhabit a wide range of aquatic environments, including oceans, seas, rivers, and lakes, demonstrating remarkable adaptability to different ecological conditions. Economically and nutritionally, bony fish are highly significant, forming the backbone of global fisheries and aquaculture. They provide an essential source of high-quality protein, omega-3 fatty acids, vitamins, and minerals, making them a vital component of human diets worldwide. The group is divided into two main types: the ray-finned fish [ Actinopterygii, which makes up the vast majority of extant fish ] and the lobe-finned fish [ Sarcopterygii, which gave rise to all land vertebrates ]. Bony fish differ from fish like sharks and rays in the chondrichthyes class; instead of cartilage, bony fish have bones. Bony fish also have a Swim bladder.

What are Bony Fish?
Bony fish are aquatic vertebrates that have a skeleton primarily composed of bone tissue. Unlike cartilaginous fish such as sharks and rays, their bodies are supported by hardened bones, which provide structure and protection. They are characterized by features such as gills for breathing, fins for movement, and usually a swim bladder that helps maintain buoyancy in water.
