The hard parts of an insect's body are on the outside and are called an "exoskeleton." The hard parts of a mammal's body are on the inside and are called a "skeleton." Although the two have some similarityes, they are not the same.
No. A snake has a solid skeleton made from bones (in the same way our skeleton is made)
No. Wasps are insects and do not have a backbone.
Essentially the same as that in any other vertebrate - including us. It is the central column of the skeleton, and the conduit for the nerve-bundle that is the spinal cord.
Crab, shrimp, and lobsters are in the same phylum as crayfish. They are all in the arthropoda phylum. Arthopods have an exoskeleton, a segmented body, and jointed appendages.
False!

The bat is a mammal and does not have an exoskeleton. It has an internal skeleton the same as other mammals do. You will find exoskeletons on insects.
Both humans and snakes have an exoskeleton made of bone and some cartilage. Both poses a skull, a jaw, vertebrae, and ribs. Some snakes also have a vestigial pelvis.
The Blue Morpho Butterfly has an exoskeleton, which is a hard outer covering that provides support and protection. This exoskeleton is made of chitin, a tough material that gives it structure and strength.

Yes. Arthropods have a skeleton on the outside, called an exoskeleton. (By contrast, vertebrates will have an internal skeleton or endoskeleton). The exoskeleton of arthropoda is made of a tough protein called chitin, a long chain polymer comparable to cellulose. It fills the same role as the protein keratin in other animals where it would be found in hair, nails, hooves, claws, beaks, etc. Some arthropods, like crustaceans, further harden their chitin exoskeleton by biomineralization with calcium carbonate. Because it is inflexible, the organism has to periodically shed it (moult) in order to grow, a process called ecdysis.
The exoskeleton on the crayfish is an adaptive advantage because it gives the crayfish support and protection. Unlike humans who have an internal skeleton, the exoskeleton protects the crayfish from its predators. In the case of support, the crayfish's ligament and muscles attach to the exoskeleton, which provides a structure for its internal organs and muscles. The internal skeleton, which provides support, does not provide the same protections as an exoskeleton; however, the exoskeleton also has its disadvantages such as molting. When the crayfish molts, it takes all the calcium out of its previous exoskeleton and holds it in two pockets in its head. The crayfish then flexes its posterior and pushes all the blood toward its anterior, cracking the shell. After climbing out, the crayfish is totally vulnerable to predators because it takes a couple days for the new exoskeleton, which has already developed but is thin and weak, to harden. The calcium stored from the old exoskeleton helps the new one harden, but it still takes a while.
An exterior skeletons (Exoskeleton) method of support is far different than an interior skeletons (Endoskeleton). The major difference is that an exoskeleton has structeres called apodemes, which are chitin structures that serve as attachment sites in the same way that muscles in an endoskeleton attach to the bone.
The same just like with all animals with an internal skeleton: to provide structure and support to the body, as well as protection to the more vulnerable organs in the body.
Crayfish have an exoskeleton, meaning that their support structure is found on the outside of their body. The skeleton is composed of one large body covering that is scleritized (hardened) in some places and left unslceritized (flexible) in others to allow for movement at joints. Humans have an endoskeleton, meaning that their support structure is found internally. The skeleton is made of hard bones that are held together at the joints by ligaments and muscles.
