Most bony fish are ray-finned (Actinopterygii). They have fins with skin over flexible bony rays. Lobe-finned fish, like coelacanths and lungfish, have fleshy fins with a limb-like structure. Both types belong to the bony fish group, each showing unique adaptations and evolutionary roles. The diversity of bony fish is immense. They occupy various habitats, from … Read more
Bony fish (Osteichthyes) can be either primary or secondary carnivores. They are diverse heterotrophs, encompassing carnivores, omnivores, and herbivores. Their diets vary widely by species. Unlike cartilaginous fish, bony fish have a skeleton made of bone. Examples include salmon and trout, which typically act as primary carnivores. Bony fish exhibit several key characteristics. They have … Read more
Bony fish use various osmotic regulation strategies. Freshwater bony fish are hyperosmotic regulators; they maintain higher internal salt levels. Marine bony fish are hyposmotic regulators; they lose water to the salty seawater. Migratory fish, such as salmon, adapt their regulation strategies based on whether they are in freshwater or seawater. The primary goal of osmoregulation … Read more
