Crabs

The heaviest spider crab, captured in 1921, weighed in at 41 pounds. For the Japanese spider crab, the largest species, 16 to 18 kg is not uncommon. Other species can be much lighter, for example in one north sea species a typical adult would be in the range of 1 to 3 kg.

yes.

Crabs can walk backwards and sideways

Hermit crabs, along with other true crabs, belong to phylum Arthropoda, all of which are invertebrates. Because of their size and other factors, the need for a vertebral column is obviated by the function of their hard exoskeleton.

The shell that the hermit crab adopts and wears and changes many times throughout his decades long lifetime helps him in several ways.

The hermit crab has a very delicate abdomen that is protected by the shell. Without this shell, his abdomen could become punctured very easily and the crab would die. The hermit crab also carries water in his shell to keep the abdomen moist. If it were to dry out, again, the hermit crab would die. The crab balances the salinity of the water within his shell by accessing fresh or salt water as needed.

The shell is also his shelter, and protects him from predators. The ideal fitting shell will allow the hermit crab to pull fully inside and to block off the opening with his large pincer.

Hermit crabs should stay in a tub of lukewarm water for around 2-3 minutes. You shouldn't bathe them any longer than 3 or 4 minutes. Depending on the type of hermit crab, there is a possibility that the hermit crab could drown, so watching the hermit crab moving is a good thing.

Bathe your hermit crab once a week. If your hermit crab is not used to taking baths, start giving him/her baths once a month and when your crabs are used this give him/her baths once a week. Clean your crab for at least 15 minutes or wait until your crab climbs out of his bathtub.

Not much can eat a horse shoe crab because of its shell, but when it is either molting or turned over sharks or larger fish can eat it.

A crab is an arthropod.

Yes. They sell them at Petco.

The crayfish's eyes can move and most of the time , it is to protect the eyes so it moves into a "case".

all that i found for you is, it eats krill shellfish and it eats about 2 times a day it can go 1 week without food! that's all.

hi good morning ,

It is interesting how crabs think and work together. I've gone crabbing on the west coast. You can put a crab in a bucket about 12 inches deep and it will easily reach up over the lip of the bucket and succeed in climbing out. But an interesting thing happens when you have 2 or more crabs in the same bucket. As the first crab reaches up to pull itself out and starts to succeed, the other crabs reach up to pull the other crab back into the bucket. They will each take turns trying to climb out while the other crabs spend their time pulling the crab that is having success back down into the bucket .

Yes. It can survive with atleast one claw..

But if it doesn't have any claws then it can survive but probably not for a long period of time with out getting killed by humans or eaten by other water predators.

I think hermit crabs are sea animals so it is unlikely you will find them living in deserts. Why dont you go to wikipedia and see what it says

They can inject poisonous venom into your body if they sting you but only really dangerous ones can kill with their sting

they live on the seashore

There are a couple parts that are orange inside of crabs. If it is soft and orange, it is most likely the hepatopancreas, which filters blood impurities in the crab's body. The harder orange material that look like beads are eggs, better known as roe.

people die all the time from eating raw shellfish - its not worth the risk IMO

It is generally bad for them due to it being processed and all, which could be very bad for a hermit crab. However they do eat pretty much everything else humans eat, except for junk food. They like:

Fruits (grapes, strawberries, apples, etc)

Vegetables ( anything:))

They can also occasionally have plain, unsalted popcorn, plain crackers, and raisins

You can look online. Possibly you will love your mole. Feed him ham. Feed him apples. Feed him clam chowder. Feeeed

Hermit crabs eat... Fresh foods and treats you can try include mango papaya coconut (fresh or dried) apples applesauce bananas grapes pineapple strawberries melons carrots spinach watercress leafy green lettuces (not iceberg/head lettuce) broccoli Grass leaves and strips of bark from deciduous trees (no conifers) nuts (unsalted nuts) peanut butter (occasionally) raisins seaweed (found in some health food and grocery stores for wrapping sushi) crackers (no or low salt) unsweetened cereals plain rice cakes popcorn (plain, air popped, can be given occasionally) cooked eggs, meats and seafood (in moderation) freeze dried shrimp and plankton (found in the fish food section at the pet store) brine shrimp fish food flakes Not sure about crabs though sorry! Hoped it helped.

A pregnant female Hermit Crab will have eggs on the side of her abdomen. She will go out to the ocean and let the eggs drift out which will sink to the bottom and grow among the plankton. When the eggs hatch the babies will dig into the sand to molt a couple times. They will then swim to shore (although most of them get eaten by fish) and be able to breathe on land. They will find shells to go into which will affect the growth of their abdomen. They will then grow by molting every 12-18 months until they die.

Mangrove crabs feed on phytoplankton as well as zooplankton. Their real name is Scylla serrata and they are often called mud crabs in addition to mangrove crabs.

the classification for chickens is poultry.

Crabs don't urinate in the typical sense. Waste from nitrogen metabolism is not concentrated into a urinary bladder like mammals; aquatic crustaceans are able to dissolve wastes directly into the water through their gills. This is important since nitrogenous waste mostly takes the form of ammonia (not urea) which is highly toxic. Studies indicate that energy expenditures for physical processes at the gills focus on uptake of oxygen, which is sparsely dissolved in water, not the elimination of wastes like ammonia, ammonium, or carbon dioxide. Because of the relative ease of elimination of the highly soluble ammonia and the more urgent need for oxygen uptake at the gills, the nitrogenous waste excretion process can be fairly described as 'passive'.
