What is the main difference between bony and cartilaginous fish?
What is the main difference between bony and cartilaginous fish?
Technically, the most obvious disparity between bony vs cartilaginous fish comes from the fact that the skeleton of bony fish is made of bones alone, while that of cartilaginous fish is made of cartilage. There are more than 20,000 fish species in the world. Of the class Chordata, Pisces is a superclass.

What is the difference between cartilage and bone?
The main difference between bone and cartilage are listed below. Bones are the hard, inelastic and a tough organ that forms part of the vertebral skeleton. Cartilage is a soft, elastic and flexible connective tissue that protects the bone from rubbing against each other. Bones are of two types: compact or spongy.

What are 3 differences between bone and cartilage?
A Cartilage is thin, flexible and resistant to compressive forces. Bones are hard, brittle and lack elasticity. They are highly vascularized and very strong. While cartilages provide cushion-type padding for long bones, bones provide skeletal support.
What is the difference between cartilage and bone Brainly?
bone form endoskeletal structure of the vertebrate. It provides support and shape to the body. Cartilage is the flexible connective tissue. matrix of cartilage is made from proteins and sugars.
What are the characteristics of cartilaginous fish?
Other characteristics of cartilaginous fish include:
- Paired fins.
- Paired nostrils.
- Scales.
- Two-chambered hearts.
- Skeletons made of cartilage rather than bone. Cartilage is supportive tissue that does not have as much calcium as bones, which makes bones rigid. Cartilage is softer and more flexible than bone.

| 4. Operculum always absent. Examples- Sharks and chimaeras. | 4. Operculum with branchiostegal membrane always present. Examples- Lungfish and coelacanth |
What differentiates the three main groups of fish from each other?
