The exoskeleton (carapace) is made mainly of chitin, also a component of our hair and nails!
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.
The body of arthropods is physically supported by an external skeleton (exoskeleton) made of a tough protein called chitin. Because it is inflexible, arthropods need to shed it entirely in order to grow in size.
Yes. Arthropods are characterized by an exoskeleton made mostly from the tough protein chitin, also joint appendages and segmented bodies.
Arthropod have exoskeleton. The exoskeleton is composed of a thin, outer protein layer, the epicuticle, and a thick, inner, chitin–protein layer.
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.
Correct, arthropods don't have vertebrae (spinal column) or an internal skeleton, instead they have an exoskeleton (external), made from a tough protein, chitin.
they all have exo skeleton
because they have no skeleton.
The external skeleton used by arthropods is called an exoskeleton.
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.
As with all arthropods, it has an exoskelton.
No, they are crustaceans which are arthropods which are invertebrates. This means they have an exoskeleton.
Arthropods are invertebrates. An invertebrate is an animal without an internal skeleton and that's exactly what an arthropod is.
The skeleton and shell of a crab are synonymous. What we'd call the shell of a crab is simply a component of its exoskeleton, the external covering arthropods use made out of a tough protein, chitin.
No. Like all insects and all arthropods, praying mantises have an external skeleton (their skin is their skeleton).
The body of arthropods is physically supported by an external skeleton (exoskeleton) made of a tough protein called chitin. Because it is inflexible, arthropods need to shed it entirely in order to grow in size.
No, they are invertebraes. All arthropods, bees included, have an external skeleton.
