There is a species of CRAYFISH that forms burrows with mud "chimneys". It may walk from the burrow so it is on land but "near water".
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.
that shell is called the exoskeleton,And the exoskeleton is a shell made out of chitin.The hard exoskeleton of a lobster is known as the chitin.
Yes. Arthropods are characterized by an exoskeleton made mostly from the tough protein chitin, also joint appendages and segmented bodies.
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.
well i don't know about non arthropods but this is what i know about arthropods:- Arthropods have jointed legs and a head and segmented body parts called the thorax and abdomen. An arthropod's body is covered by a shell or a hard outer skin called an exoskeleton. It is made of a material called chitin. The exoskeleton has a special top layer, the cuticle, which is thick and tough. In crustaceans, the exoskeleton is sometimes called the carapace and hides the segmented body parts. by kira 7G

An arthropod is an invertebrate. It has to have a hard shell and more than 2 legs. Wasabi from Ben Ashmore
A creature, such as a lobster, shrimp or crab that has no backbone, a hard outer shell, and usually lives in the water.
I believe "arthropod" is the word you're looking for.
A Sea Turtle
A turtle. and define what you are thinking is a "protective shell"
A Sea Turtle
An example of a reptile with a hard shell that lives on land is a tortoise. Tortoises have a thick, hard shell which provides protection from predators while they move on land. They are typically herbivores and are known for their longevity.
Coconut. It has a hard shell that stores water from the plant's growth and development.
No they do not. They have a hard shell (exoskeleton) instead.
When an insect sheds its outer skin, it's called molting.
