Answer:
Step-by-step explanation:
No, ray-finned fishes do not have a cartilaginous skeleton. They have a bony skeleton, which is made of ossified tissue. Cartilaginous skeletons are found in sharks, rays, and skates.
Ray-finned fishes are the largest group of vertebrates, with over 27,000 species. They are found in all aquatic habitats, from freshwater streams to the deep ocean.
Bony skeletons are stronger and more rigid than cartilaginous skeletons. This gives ray-finned fishes a number of advantages, including:
Increased speed and maneuverability
Better protection from predators
The ability to support larger body sizes
