Yes crustaceans do molt because they have exoskeletons meaning they have and outer shell. I believe. every 2 years or months they molt out of their shells. in other words, they leave their shell
All animals with exoskeletons, including crabs, molt.
yes they do?
they use their muscles
because they feel like it
yes
Crabs grow out of their shells and they also shed their skin to do that. Meaning they molt their skin.
yes acoshonly
Yes, they must molt in order to grow.
No, when they molt their underground, so they get out of their shell, molt, get back in their shell and eat the exoskeleton. You have to let them eat it because it has the nutrients it needs.
Birds and reptiles both do. Some insects and arachnids molt. Birds molt feathers from time to time. Reptiles molt their top layer of skin. Animals with exoskeletens, such as hermit crabs, also molt.
Invertebrates, because they need to molt to grow. Hermit crabs molt underground and can stay there for weeks to months to learn more about molting please follow the link below this answer. Thanks ;)
Yes, crabs legs can come off if they do they will grow back when they molt so don't worry!
