No! They are made of cartilage.
They have a cartilaginous skeleton, but are in the phylum chordata, which is for vertebrates.
no they do not .

Sharks do have backbones, making them vertebrates. Their skeletons are made mostly of cartilage and not actual bone, being of a more ancient classification of fish in evolutionary terms. Whether something is cute or not is subjective, however sharks aren't exactly an animal that have the head/body porportions similar to what humans usually see as cute, they don't look neotonous (like babies).
No cicadas do not have backbones, they are invertebrates. Any Animal and insects that is an invertebrates do not have backbones.
because they have backbones and without backbones they would die.
no they do not have backbones if a worm do not have a backbone then a thousand led do not have a backbone 😱💪
no they don't have backbones
sharks have backbones and they are fish
Animals that have backbones are considered vertebrates, while animals without are invertebrates. So sharks, having backbones, are vertebrates.
Sharks and their relatives have cartilage.
It is a vertebrate. They have backbones.
There are about 58,000 known species with backbones, these include; sharks, mammals, birds, amphibians, reptiles, rays and (some types 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.
Yes, but they are different from other vertebrates in that their backbones are made of cartilage, like the rest of their skeletal structure.
sharks dont have bones... their skeleton is made of cartilage
Sea animals with backbones include fish, sharks, whales, dolphins, and sea turtles. These animals are known as vertebrates because they have a backbone or spinal column.
