Cartilage ! Not silica!!
What materials make up the endoskeletons of most vertebrates
The animals that have endoskeletons are all vertebrates like lions, tigers, dogs, cats, etc. The animals that have exoskeletons are crabs, most insects, mullusks, clams, etc.
You do. rabbits. Sparrows. Dogs. Cats. Frogs. Dude.I believe people, most animals and fish have endoskeletons. Insects and shellfish have exoskeletons.
The endoskeleton is an internal skeleton. Human beings and other mammals have endoskeletons. Basically, any animal with their bones on the inside has an endoskeleton.
Tissue and Blood!.
Endo = inside. Endoskeletons are skeletons like ours, bones on the inside. Arthropods have EXOskeletons, armour on the outside.All arthropods have segmented bodies with tough exoskeletons made from chitin.
vertebrates
A true endoskeleton is derived from mesodermal tissue.
Fish with a skeleton made of bone are classified as bony fish, or Osteichthyes. This group includes a wide variety of species, such as salmon, trout, and goldfish. Bony fish possess a skeleton primarily composed of calcified bone, contrasting with cartilaginous fish like sharks and rays, which have skeletons made of cartilage. Bony fish are the most diverse group of vertebrates, making up a significant portion of all fish species.
Yes, most fish species have backbones, therefore are vertebrates.
since rats are mammals, they are most definitely vertebrates.
Five organs that are found in most vertebrates are the brain, stomach, heart, eyes and skin. Vertebrates are animals that have a spine.
