that shell is called the exoskeleton,And the exoskeleton is a shell made out of chitin.
No, it's the outside of a mollusc, such as a snail, slug or squid. Arthropods are animals such as insects, crustaceans and arachnids, with a hard exoskeleton as their outside covering.
The external covering on arthropods is called the exoskeleton (or cuticle). It is made of a tough protein called chitin, a long chain polymer comparable to cellulose. Because it's inflexible, arthropods need to shed it (moult) in order to grow.
An arthropod
Arthropod means "jointed legs," because arthropods are covered with a hard skin ("crab shells" are the hard skin of crabs) and they move by flexing joints along their hard skin. When they grow, they have to grow inside their hard skin. But, if the skin is too tight, there's no space! By taking in air or water when their shell is still soft, arthropods can "pump up" and make a nice roomy shell to grow in. When they fill that shell up, they crawl out of it, and then pump up the soft skin underneath. The pumped up soft skin hardens into hard skin, and the arthropod is ready to keep growing.
If you're going to be classified as an arthropod, you'd need to have a segmented body, an exoskeleton made from chitin, and joint appendages.
Chitin
No, it's the outside of a mollusc, such as a snail, slug or squid. Arthropods are animals such as insects, crustaceans and arachnids, with a hard exoskeleton as their outside covering.
An arthroderm is an external covering of an arthropod.
It is called the exosketon. It is made from a hard protein, chitin, which arthropods often biomineralize for further strength.
Exoskeleton/ Chitin
The exoskelton of an arthropod is hard, and thus cannot accomodate growth. So an arthropod must periodically replace it.
The external covering on arthropods is called the exoskeleton (or cuticle). It is made of a tough protein called chitin, a long chain polymer comparable to cellulose. Because it's inflexible, arthropods need to shed it (moult) in order to grow.
YESSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS they do have have hard covering.
Arthropods are invertebrates.They have jointed legs, segmented bodies and hard outer covering known as exoskeletons which the shed from time to time as they grow.Insects,centipedes,millipedes,arachnids and crustaceans are different example of arthropods.
hard covering
what is the hard covering and the jointed legs of the crabs
No arthropods are organisms with a hard exoskeleton goats have a bone skeleton
