yes.
The armadillo, like all mammals, has an endoskeleton (inside structure of bone and cartilage) that supports the organs and muscles. The exterior scales of an armadillo are bone and horn, but do not constitute an exoskeleton.
Endoskeleton
To Allow Growth And Increase In Size.....
Chipmunks, like all mammals, have an endoskeleton, which means their bones are internal. An exoskeleton is a hard outer covering found in arthropods like insects and crustaceans. Chipmunks do not have an exoskeleton.
The antonym of exoskeleton is endoskeleton. An endoskeleton is an internal skeleton found in vertebrates, whereas an exoskeleton is an external skeleton found in arthropods and some other invertebrates.
The presence of segmented bodies with jointed appendages is the characteristic that most distinguishes arthropods from other invertebrates. This feature allows arthropods to exhibit a wide range of movement and adaptability in their environments.
Correct, backbones are missing from arthropods because they are exoskeletal, having a tough outer skeleton rather than an internal skeleton (endoskeleton) like mammals, reptiles, amphibians, and so forth.
An exoskeleton is a flattened immovable endoskeleton made up of fused plates. This rigid structure provides support and protection for the organism, such as seen in arthropods like crabs and lobsters.
They have muscles like us, except theirs are smaller and are connected to the inside of their exoskeletons, instead of wrapping around the endoskeleton like we have.
Endoskeleton
Endoskeleton - their bones are inside their body
Arctic foxes are mammals and have internal skeletons (endoskeleton).
Endoskeletons. Arthropods such as lobsters, insects, and shrimp have exoskeletons. Endoskeletons have a skeletal system inside thier bodies, while exoskeletons have hard outer shells.
