Yes they do. Cartilage is also found in your nose and ears!
Sharks and their relatives have cartilage.
Vertebrates are animals that have a backbone and an internal bony skeleton and include fish such as barracudas.
No! They are made of cartilage.
All true fish have backbones. It is part of the definition of "fish."
Sharks are vertebrates (they belong to the phylum Cordata), so they have a spinal chord. However they are also cartilaginous fishes (they belong the the class Chondrichthyes) meaning that their skeleton is made of cartilage instead of bone. They do have a cartilage sheath that surrounds their spinal chord which could be considered a spine. There could be a semantic debate over whether that constitutes a spine, but I for one think it does.
bony; the only cartilaginous fish currently in existence are sharks, skates, and rays.
Yes, rays are cartilaginous fish, which means they have skeletons made of cartilage rather than bone. So, rays do not have backbones like bony fish, but they do have a flexible skeletal structure that helps support their bodies.
Fish who are made of cartilage.
yes and the wiki answers are a lay don't believe in thi
sharks dont have bones... their skeleton is made of cartilage
One difference is that fish are bony. Sharks have a skeleton made of cartilage (like in your nose or kneecap). Sharks have five to seven gill slits, while fish only have one. Fish have swim bladders for bouyancy, sharks do not.
Yes, fish have backbones. They are vertebrates, which means they have a spinal column made up of individual vertebrae that protect their spinal cord. This backbone allows fish to swim and move efficiently.
