Pea crabs for one. Fiddler crabs for two.

Valve means shell. A snail is a univalve because it only has one shell. Crabs are not considered bivalves. The bivalves are a group of mollusks which includes clam, mussels, and oysters, all of which have two shells enclosing the animal, hence their classification as bivalves.
No, Hermit Crabs and Fiddler crabs require two different environments. The Hermit Crab would drown in the water a Fiddler Crab needs. You can always ask your local pet store if there is any way possible though. Some hermit crabs live on land others live in water even land hermit need two enter salt water , fiddler crabs are brackish or fresh hermit crabs can't breathe in those environments
No, they both have two claws. One large one and one small one.
Both are Crustaceans. They are invertebrate, as they have an external hard shell, and no internal skeleton. They both have two arms that have pincers (claws) on the end. Though they live in water, they can come out of the water, provided they don't dry out. They are also scavengers.
Hermit crabs are very social and LOVE company they usally don't live as long as they do when their with others. They can live over 2 years mine lived for 3 years. Hermit DO FIGHT they fight over shells. one likes a shell the other has (make sure your hermies has alot of shells, NOT over crowding the tank!) and they fight. The victim usally dies over the fight. But if you are there when it happens, you should blow on them if they still fight pick them up (do NOT pull them one will lose a limb!) if that doesn't happen you need to LIGHTLY mist them with distilled water.
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.
1 month Another view: I honestly don't know how long they can live, but they can easily return to a tank that is not kept clean. Try to figure out what attracted the mites to your tank in the first place, and correct that so it won't happen again. Mites can be extremely painful and dangerous for your crabs. A good ocean-salt bath will kill the mites on your crabs (make sure it is an approved ocean salt, not table salt or sea-salt meant for humans, which is deadly to hermit crabs because of additives). Follow this link to get excellent information on getting rid of mites and keeping them out of your crabitat:
It can either be one word (seashell) or two (sea shell)
Depending on its size, a crab can go up to two weeks without food. Crabs eat very little and it store water in the back of its shell to moisture its gills.
