The shell is used for protection against predators, to hold water when burrowing or experiencing drought, and to regulate body temperature. (If the temp is high crabs will find thinner shells, and thicker for lowered temps.)
I'm not sure what you mean by this question. Hermit Crab is a term used to refer to many different species of crabs that live in shells that have been cast off by snails. They can be marine hermit crabs, or land hermit crabs. Within these categories there are many different species. The Genus Coenobita contains 16 different species of terrestrial (land) hermit crabs. The Genus Paguras refers to those species of marine hermit crabs.
Hermit crabs are scavengers. Litterally. They scavange for food and they scavange for houses. When they outgrow their old shell they look for a larger abandoned shell. Their shell is not grown by them. It used to belong to a shellfish.
Yes! It is very important that a hermit crab has a shell, it is used to protect their bodies. It also saves them from getting eaten by other animals! Though sometimes, you find hermit crabs that haven't found a shell that isn't the right size or shape, and instead of a shell, they might carry things like bottle tops. Usually, hermit crabs try to avoid situations like this but, when they urgently need to change into another shell because their current shell is too small, it will be unavoidable.

Besides the use of the shells of other animals hermit crabs have many other adaptations. Land hermit crabs have developed modified gills that allow them to live on land. They use the humidity in the air to breath and their shell water to lubricate their gills. Hermit crabs have one small feeding claw and one large defence claw. When retreating into their shell the defence claw seals the opening protecting the hermit crab inside. The defence claw can also be used in dominance displays towards other crabs. Or to scare off small prey. It has a powerful pinch and a hermit crab will hold on until they feel safe once more. Because land hermit crabs moult they have the ability to regenerate damaged or missing body parts. Legs, claws, anteni, eyes can all be regrown in one or two moults depending on the health of the animal. They have a strong sense of smell. they can detect food from distances away. They like to try new foods every day and can remember the smell of a previous meal. Land hermit crabs have adapted to live in large colonies. The safety in numbers helps defend them against predators. They will also find food together. Hermit crabs are scavengers and will rarely eat live food. This adaptation lets them scour the beaches or ocean floor and enjoy the left overs of other animals. They will eat both animal and plant matter.
Hermit crabs are believed to have originated in the marine environment and have evolved over time to adapt to living on land. They are commonly found in tropical and sub-tropical regions worldwide. Hermit crabs have a unique behavior of using empty shells as protective homes, which has contributed to their success in various environments.
yes you can play with hermit crabs but not the way you think.all you have to do is let it crawl on your hand or on a flat surface,but that's about it.(if your hermit crab is not used to you it may pinch you if you try to hod it)
2 clawsLand hermit crabs have 2 claws. The larger claw is used for defense and to cover the hole opening of their shell for protection. It is also used to assist with climbing and the one they normally hold on with. It also breaks chunks of food off for easier eating which is then broken again with the smaller claw and passed to the mouth. The smaller claw is mainly used to break food for eating.
Hermit Crabs can use cocanut husk, or soil that you get from any pet store used for reptiles. Hermit Crabs also use sand, they need a wet and also dry climate. If you get oil from the ground, you must bake it or freeze it in a really hot or cold temp. for a long while.
There are over 5000 species of Crabs in the whole world but only 4500 species are true crabs the other 500 crabs are hermit crabs which are not 'true' crabs.According to The World of Animals. by Walters, Martin & Johnson, Jinny. (Published by Parragon, 2007) 6,793 different species of crabs are known.In addition there are about 850 species of freshwater or semi-terrestrial crabs.'True' crabs are decapod crustaceans of the infraorder Brachyura, whereas hermit crabs [decapod crustaceans of the superfamily Paguroidea] are classified quite differently due to physical characteristics. They are not even closely related to 'true' crabs. For more information, see Related Links below ads...
Interact? Hermit crabs and humans are not like. That being said however: Hermit Crabs and humans do both need to eat, and both have their own food pyramid they should eat from to remain healthy. Hermit crabs and humans both need to drink water so they do not become dehydrated. However, water needs to be safe as in hermit crabs if offered tap water needs to have a dechlorinator used to make it safe, whereas humans do not. Hermit crabs and humans both need a certain warmth to prevent hypothermia which can lead to harmful complications or death. Hermit crabs and humans both need salt in their diet even though it is a different type of salt. Hermit crabs need the elements found in ocean/sea water salt/salt mixes and humans need the iodine from salt.
There used to be stands or booths were they sell hermit crabs at the mall well at least they do that at my mall not sure if they do that at other malls You could also check your local pet store...they are bound to have some there : )
