Crabs

The limpets have a hard shell because it acts as a barrier to wave action. The shells are smooth on the inside and can be either smooth or ribbed on the outside.

No, by no means are green crabs (carcinus maenas) endangered. In some parts along the European coast, they're considered pests.

When male and female crabs reproduce, they assume the doubler position, which is when the male carries the female. Mating lasts about five-and-a-half hours, but the crabs may stay in this position for up to three days afterward. The female stores the male's sperm on the underside of her abdomen, where it will be used for two more spawnings that occur within her three-year lifespan. The females migrate to slightly saltier waters after mating and attach between 100,000 to two million eggs to the sperm stored under the abdomen. The incubation period lasts about two weeks, until the crab larvae hatch and are released into the ocean to fend for themselves. For the next 40 days, the crab larvae continue to grow until they reach the adult crab stage.

Cockroaches are distantly related to arthropods such as spiders (arachnids) and crustaceans (shrimp, crabs and lobsters). Cockroaches are insects (Class Hexapoda) and lobsters are decapod crustaceans (Class Crustacea). The term 'roaches of the sea' reflects the behavior of lobsters as omnivorous scavengers. Cockroaches will eat almost anything organic and so will lobsters. They clean up the dead and dying plants and animals in their environment.

blah blah blah

Neither of these animals lives in a freshwater aquarium environment. They are creatures of the sea shores, beaches and mangroves.

usually the girl hermit crabs have a lighter color Female crabs have "privates" called gonopores. They are two little dots located on the back pair of walking legs. You can find a picture by going to this sight: http://hermit-crabs.com/sexing.html

If you stick your finger at them they might pinch you....with their claws....

Depending on how old they are. They molt less when they are older and molt more often when they are younger. If they have enough calcium to molt or not. Generally every 1-2 months.

Not all of them have "shells," but all of them have exoskeletons, which are essentially the same thing.

on a male horseshoe crab, the two front appendages look like boxing gloves. They use these to hold on to the female when they mate. on a female the two front appendages just look like regular claws

yes but make sure the fish are big so the crayfish cant eat them

The crab's exoskeleton helps and supports its body. It protects the soft body of the crab. It is also waterproof, so it will protect it underwater, too.

No. They just miss out on the extra protein they would have gotten.

yes i use to have one and we kept him in a tiny plastic cage but no netting on the edge make sure its safe though it probably depends on the crab. If it is a small crab you could put it in a plastick cage, but when it gets older and bigger you might want to change it. good luck!!

Horseshoe crabs are not a fish, it is a marine arthropod. The horseshoe crab is more closely related to spiders, ticks, and scorpions than to crabs.

i work in a pet store and i do know that Fiddler crabs eat microscopic critters that show up in the sand as well as algae. The crabs sift the sand with their claws (or claw if its a male crab) and get nourishment from the microscopic particles and bacteria in it.

...but as far as fish go, they are not the type to stalk their prey, they would rather have a wounded or weaker fish sort of drift by and then attempt to grab it. So you could possibly try some small minnows or maybe even the smaller goldfish (it all depends on the size of your crab). HOPE THIS HELPS :)

Sushi restaurants sell raw fish as one of their main types of dishes so some people worry about food poisoning. This is unlikely though because the restaurant will maintain high standards of hygiene.

i got clocked out and i was flying at 13.9mph down a straight a way yesterday

It could be a few things or a combination of them. Most likely the crab is stressed or sick. This can happen if it's by itself (hermit crabs live in large colonies in the wild), if it's tank environment is not suitable (you need 80 deg F, 80% humidity, moist coconut fiber or sand substrate, etc) or not getting the right nutrition ("hermit crab food" sold at pet stores often contains hermful chemical and preservatives), not the right kind of water (they need deep dishes of both fresh and salt water). Or he could have been attacked by another crab.

King crab, opilio, coconut

Yes, they like sugar, but dont feed sugar directly. Hermit crabs like the natural sugar from fruits, such as Grapes, Apples, Pineappes, Coconut, Mango, and many other fruits!

your hermit crabs are burrowing because they are about to molt. hermit crabs have exoskeletons so they have to molt or shed their exoskeleton to grow. so they dig underground to do that because hermies are vunrable they will stay underground to weeks to months NEVER dig them up. you know if they are dead if you smell rotting egg.
