Question

Which Fish Isn't Cartilaginous?

Answer 1

Cartilaginous Fish:

1. Cartilaginous Fish are the oldest jawed vertebrates still living, and their skeleton is formed of cartilage, as the name suggests.
2. Sharks, rays, and skates are among them, as are chimeras.
3. Jawed fish having paired fins, paired nostrils, scales, two-chambered hearts, and cartilage rather than bone skeletons are known as cartilaginous fish.
4. Cartilaginous fishes are apex predators that play a significant role in a variety of aquatic habitats, influencing the balance of species abundance and richness.
5. The skeletons of sharks, rays, skates, and chimeras (sometimes known as rat fishes) are all cartilaginous.
6. Sharks can travel fast through the water because cartilage is less dense than bone, allowing them to conserve energy. Examples are Blacktip Reef Shark, Bonne ahead Shark, and Electric Rays, Epaulette Shark.
