Shark teeth are sharp and horse teeth are flat on the tip. Shark teeth are smaller than horse teeth. Horse teeth are big and you can tell how old they are just by their teeth! :)
A shark's vertebrae is made of cartilage, whereas a horse's is made of bone and cartilage.
Sharks indeed have a backbone. End of story.
they have a backbone
Sharks Dont have a "backbone" persay, but they do have a special interior bone like thing. (thats the best way i could put that) The bone like thing consists of catrilidge. which acts somewhat as a "Backbone".
No. an invertebrate is an animal without a backbone.
well the main difference is that a horses spine is made of bone while a sharks is made of cartilage.
A vertebrate has a backbone and an invertebrate does not have a backbone
Around 3% of animals are vertebrates (animals that have a backbone). This includes approximately 64,000 species. Examples of animals that have a backbone are; sharks, reptiles, mammals and birds.
There are two subclasses of cartilaginous fish. Elasmobranchii and holocephali. The subclass elasmobranchii encompasses sharks. The subclass holocephali encompasses rays and skates.Sharks, skates, and stingrays.
dependant on which sharks you are talking about all sharks are different in one way or another as most sharks determine other sharks personalitys
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 a gorilla does have a backbone but the backbone is different to a human bone
ALL SHARKS ARE NOT DANGEROUS TO HUMANS BECAUSE THERE ARE DIFFERENT KIND OF SHARKS AND DIFFERENT KIND OF PEOPLE. ALL SHARKS ARE NOT DANGEROUS TO HUMANS BECAUSE THERE ARE DIFFERENT KIND OF SHARKS AND DIFFERENT KIND OF PEOPLE.
