Cartilaginous fish are a group of fish belonging to the class Chondrichthyes, which includes sharks, rays, and skates. Unlike bony fish, which have skeletons made of bone, cartilaginous fish have skeletons made of cartilage, a tough and flexible tissue. This adaptation allows them to be more lightweight and agile in the water.

Shark Vertebrates and Invertebrates

Here are some key characteristics of cartilaginous fish:

1. Skeleton: As mentioned earlier, cartilaginous fish have skeletons made of cartilage rather than bone. This cartilaginous structure provides support and flexibility to their bodies.

2. Body Shape: Cartilaginous fish have a streamlined body shape, which helps them move efficiently through the water. Their bodies are typically dorsoventrally flattened, allowing them to glide smoothly.

3. Skin: The skin of cartilaginous fish is covered in tooth-like scales called dermal denticles. These denticles reduce drag and turbulence in the water, enabling the fish to swim faster.

4. Gills: Like other fish, cartilaginous fish respire through gills. They have gill slits located on the sides of their bodies, which extract oxygen from the water as it passes over the gill filaments.

5. Reproduction: Cartilaginous fish exhibit various reproductive strategies. Some species are oviparous, meaning they lay eggs that hatch externally. Others are viviparous, giving birth to live young after internal development. There are also some species that are ovoviviparous, where the eggs develop internally, but the young are hatched inside the female and then born live.

6. Sensory Organs: Cartilaginous fish possess a well-developed sensory system. They have a keen sense of smell, aided by the presence of olfactory organs called olfactory rosettes. They also have a lateral line system that detects changes in water pressure and helps them locate prey and navigate in their environment.

7. Predatory Nature: Many cartilaginous fish are apex predators in their ecosystems. They have sharp teeth and powerful jaws that allow them to capture and consume a variety of prey, including other fish, invertebrates, and even marine mammals.
