The answer is: some fish have bones, while others have skeletons made of cartilage.
Here's a more detailed explanation:
Fish are a diverse group, and their skeletal structures vary. They can be broadly categorized into two groups based on their skeletal composition:
-
Bony Fish (Osteichthyes): These fish have skeletons made primarily of bone, just like humans. Examples include salmon, tuna, and goldfish. Their bony skeletons provide strong support and structure.
-
Cartilaginous Fish (Chondrichthyes): These fish have skeletons made of cartilage, which is a flexible and less dense material than bone. Sharks, rays, and skates fall into this category. While cartilage doesn't have the same rigidity as bone, it offers flexibility and buoyancy.
So, to summarize, whether a fish has bones depends on the species. Some fish have bony skeletons, while others have cartilaginous skeletons. Both types of skeletons are well-suited to the lifestyles of these different fish.
