Crabs

Crabs will hide under rocks after they have molted while their new shell is soft. During this time they are very vulnerable to predators. The time it takes for their shell to harden varies by species but for some it is a few days.

It all depends where you get the Hermit Crab from. I got two Hermit crabs when i got mine. I got two Hermit Crabs and two shells and plus all of the other stuff I had to save up about $230-$250 dollars just to be safe. Because you never know you might find something at the store that you think your Hermit Crab just HAS to have. I know I did. TIP: I have also found that PetSmart is a little bit cheaper than PetCo, especially if you have one of their cards. And it's not that much cheaper than PetCo, BUT in the long run it will eventually pay off. I know that it helped me out.

You can get them at local hermit crab ( pet stores ). You can get it at stores that sell hermit crabs. Commercial brand foods for hermit crabs aren't good for them. Feed them a variety of food that you would eat. Food that you buy in the store has harmful preservatives and does not have enough nutrients that the hermit crab needs..

Crustacean (the group that contains crabs, lobsters, and shrimp) shells are made of a material called chitin, which is naturally hard and brittle. Softshell crabs are those who have just shed their exoskeleton. It takes a while before their hard chitinous shells grow back.

The Crab belongs to:

Kingdom: Animalia
Phylum: Arthropoda
Subphylum: Crustacea
Class: Malacostraca
Order: Decapoda
Suborder: Pleocyemata
Infraorder: Brachyura

The hard shell of a lobster is known as the chitin.

I would belive it would be exothermic. This is just a guess, but crabs live underwater mostly; They are exposed to diffrent tempertures. I am not sure about their homoeostasis, but they are exposed to many mixed temperatures, so it would be hard to keep an internal temperature going.

just tie a fish to a long tread, and place it near crabs hole ,as soon you keep you go away from that hole holding that another end of thread,the crabs will come to eat the fish within some time . it will

Crabs shed their exoskeleton to get more space. It usually means that they have grown out of their shells.

That would depend on the kind of crab you're talking about. The typical lifespan of a mud crab is thought to be 3 or 4 years while hermit crabs have an average lifespan of 10 years but can live up to 30 years.

A fish has gills which allows it to breath underwater. It also has fins to move very quickly and some fish are even camouflage to disguise them under the water. This is how a fish adapts to their environment.

Crab classification:

Phylum - Arthropoda

Subphylum - Crustacea

Class - Malacostraca

Order - Decapoda

Crabs are born from eggs. As babies, they don't have shells, but float among the other larval stages in the plankton. As they grow, they develop a shell and settle down on the bottom of the sea (or sometimes move onto land in the case of several species).

They generally get a cut of the profits made from selling their catch. $20 to $50,000 per trip.

It depends on the type of crab. For example, fiddler crabs are of the genus Uca (Ocypodidae). And the blue crab is in the genus Chionoecetes.

cheese on toast. that's what they eat.

the yeti usually eats raw yak but they now survive of ice chips and plants. occasionally a couple mountain goats roll up and get muched on

You can tell a fiddler crab's gender by its claws. A female fiddler crab has two claws, the same size. A male fiddler crab has one large claw and one small claw.

No.

Crayfish: a nocturnal freshwater crustacean that resembles a small lobster and inhabits streams and rivers.

Crab: a crustacean with a broad carapace, stalked eyes, and five pairs of legs, the first pair of which are modified as pincers.

No, sometimes they're white, sometimes they're more of an orangey color than red. If you would like to know something really interesting about crabs, their blood is blue. Their blood is blue due to the presence of copper in it.

Lobsters do not have internal skeletons, but they do have external skeletons (exoskeleton), which are their shells.

You NEVER should remove a crab from ti's shell!! unless it's dead or something

crabs live in the high zone and in the splash zone

Every living thing must take in substances which provide energy/nutrition. The unusable parts of the substances must then be excreted. In most species a crabs shell is not actually completely one whole, enclosed space. Just as with a turtle, many crabs have an opening in it's shell for this purpose. However, hermit crabs are not actually related to the crabs that most people think of. They are antropods. As the answer before this one (it was auto flagged for some reason) said, hermit crabs do use their claws to scoop out the excrement because their shells, while not their own originally, are completely one piece and a part of their abdomens and last 4 sets of legs are always inside the shell except when they are molting.

The lifespan in captivity is about 13 years. In the wild it is an average of 11 years.
