By definition, arthropod skeletons are external, a defining characteristic of the phylum; having both an internal and external skeleton would be redundant.
Arthropods are invertebrates. An invertebrate is an animal without an internal skeleton and that's exactly what an arthropod is.
No, at least not in the backbone sense. Arthropods have their skeleton on the outside (exoskeleton); spines or vertebral columns are characteristic of vertebrates under a different phylum - Chordata, including fish, birds, mammals, etc.
Correct, arthropods don't have vertebrae (spinal column) or an internal skeleton, instead they have an exoskeleton (external), made from a tough protein, chitin.
Arthropods use external skeletons (exoskeletons).
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.
yes it has an exoskeleton Ants belong to a phylum called the arthropods. Arthropods have shells, which are classified as a type of external skeleton or exoskeleton. They do not have internal skeletons of the type that we vertebrates have.
No, rabbits are chordates - phylum Chordata, a different phylum than Arthropoda (the arthropods). Pretty much anything with an internal skeleton and backbone like mammals, birds, reptiles, amphibians, will be chordates. Arthropods have their skeleton on the outside (exoskeleton), like the insects or crustaceans.
No, tigers are chordates - phylum Chordata, a different phylum than Arthropoda (the arthropods). Pretty much anything with an internal skeleton and backbone like mammals, birds, reptiles, amphibians, will be chordates. Arthropods have their skeleton on the outside (exoskeleton), like the insects or crustaceans.
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.
they all have exo skeleton
Arthropods is an exoskeletons, their components are external. This supports and protects the aminals inner body. No internal backbone
Yes, having an exoskeleton is a defining characteristic of arthropods. Animals with internal skeletons belong to three other phyla, for example Chordata - the chordates, including mammals, reptiles, amphibians, etc.
