Since the different elephant species have different numbers of thoracic, lumbar, sacral and caudal vertebrae, an elephant’s skeleton consists of 326 to 351 bones.
Does a mammals have an endoskeleton or exoskeleton? Mammals, reptiles, birds, fish and amphibians are vertebrates with endoskeletons (skeletons inside their bodies).

Can an animal have an endoskeleton and exoskeleton? Some animals contain exoskeleton, some contain endoskeleton and some have both of them. Exoskeleton is mainly found in the vertebrates like reptiles, fishes and mammals. It is the living structure which protects the internal organs.

Is there a mammal with an exoskeleton?

Do crabs have exoskeletons?
Crabs, lobsters, shrimp, barnacles and many other animals belong to the phylum arthropods. All arthropods have a hard exoskeleton made of chiton, a type of protein. This shell provides protection for the animals, and gives support for the attachment of the arthropod’s muscles.
Is an elephant’s trunk a limb?

What material is elephant Trunk made of?
The trunk is composed of 140kgs of flesh, fat, nerves, connective tissue, and over 40 000 muscles grouped around the nasal passages. These taper down to two fingers in the case of African elephants and one finger for Asian elephants. Functionally, the muscles are what give the trunk its versatility.
Are elephants Digitigrade or Plantigrade?
The hind limb and foot of the elephant are oriented semi-plantigrade, and closely resemble the structure and function of the human foot. The tarsals and metapodials are arranged so as to form an arch, similarly to the human foot.

They are a special type of fish known as “elasmobranchs”, which translates into fish made of cartilaginous tissues—the clear gristly stuff that your ears and nose tip are made of. Even though sharks don’t have bones, they still can fossilize.
Do starfish have exoskeletons?
Starfish have an endoskeleton.
This skeleton is made of calcium carbonate plates known as ossicles and forms granules or spines.
Does a spider have an exoskeleton?
Spiders are invertebrates. That means that they don’t have a skeleton like we do. Instead they have an exoskeleton. This is a hard, protective outer layer made of overlapping layers of chitin (a natural polymer) and protein.
Do squid have bones?
