How many leg's do a crab have?
I think they have have 6 legs including the pinchers. But many loose a leg or two during their lives.
Can a fresh water crab live in a tank without a filter?
Many types of crayfish and crabs can coexist peacefully. However there are a few caveats. 1) Be sure that your FW crabs are truly suited to freshwater. Osmosis (the transfering of liquid across membranes to "equalize" the particle densities) can kill your crabs if they are a brackish (FW/SW mix). 2) Different species of crabs and crayfish have varying degrees of aggression. Some species would rather hide than fight... others would rather fight than hide. This also means that the more aggressive species (in my experience the crab) will get all the food while the cowardly species will starve. 3) Beware of size differences. Many species of crayfish will out-size crabs, possibly moving the crabs into the realm of 'lunch'. 4) If you are only planning on having an 'invertebrate' tank (no fish, just crustaceans), good. Some fish will be quickly torn apart by some species of crabs or crayfish. 5) Many humans enjoy the taste of crustaceans. So do many fish. So, to finally answer your question: maybe, it depends, yes, no. Careful research can lead you to find compatible crabs, crayfish and fish. Good luck!
A lot of people call it crab butter. But it is really an organ in crabs called the hepatopancreas, which functions mainly in digestion.
How long can you keep a blue crab alive after you catch it?
If their gills are kept moist, blue crabs can survive for 24 hours or a bit longer out of water. The typical life expectancy for blue crabs is 1 to 3 years, though they have been known to live as long as 8 years.
How can you tell if hermit crab sleep or dead?
if it smells its dead if it doesnt its not. it usaull comes out at night because they are nocturnal.plus hermit crabs are oderless so if they smell they are dead
Can hermit crabs live on rocks?
oh yes. they are pro escape artists and will find all sorts of crazy ways to get out of the tank and explore.
hermit crabs are very smart. They can find some tricky way to get out. make sure you have the proper top for you tank unless you want to find a hermit crab on your bed.
Can you get crabs from kissing someone with crabs?
not unless they have pubic hair on their face. if this is so, i am very sorry... for both of you..
Yes. Hermit crabs eat fruits, veggies, lean (non fatty) not seasoned meats, egg yolk, egg white, egg shell (rich in protein).
Stay AWAY from human foods, such as peanut butter twinkies, and COMMERICAL FOOD, it has harmful preservatives (no matter what it says), and little or no nutrients.
My hermies absolutely LOVE SEA salted nuts, it has to be SEA salted, because table salt sofacates and kills hermies.
Have does a spider crab survive?
both, they eat creatures smaller than themself, and larger animals prey on them.
How do you make crab apple jelly with no sugar?
4 cups crabapple juice (about 3 pounds of crabapples and 3 cups water)
- 4 cups sugar
Yields: 5 or 6 half-pint jars
Procedure: Sterilize jars, rings, lids, and all prep tools and surfaces before beginning.
Making the Juice:
Select firm, crisp crabapples, about 3/4 lb. firm and ripe, and 11/4 cups fully ripe, slightly soft or yielding to pressure. Sort, wash, and remove stems and blossom ends; don't pare or core. Cut crabapples into small pieces. Add water, cover and bring to boil on high heat. Stir to prevent burning or scorching. Reduce heat and simmer for 20 to 25 minutes, or until the crabapples are soft. Do not overcook; excess boiling will destroy the pectin, flavor, and color; so, timing is important. When the fruit is tender, pour everything through a double layer of damp cheesecloth or a damp jelly bag. Suspend the bag over a bowl or pan, using a stand or colander to hold the bag. Drain the juice without pressing or squeezing, which will cause cloudy jelly. If a fruit press is used, the juice should be restrained through a jelly bag.
Making the Jelly:
Measure the juice into a saucepot. Add sugar and stir well. Boil over high heat until the temperature measures 220°F (this is for sea level). The test for doneness is when the jelly mixture sheets from a metal spoon. (See the three jellying tests below).
Remove from heat; skim off foam quickly. Pour hot jelly immediately into hot, sterile jars, leaving ¼ inch headspace. Wipe the rims of the jars with a dampened clean paper towel; lid and ring the jars. Place jars in a water bath canner as you go.
Process in the canner by altitude. Beginning at five minutes, boil for an additional five minutes for every 6,000 feet over 1,000. For instance, sea level to 1,000 feet, boil five minutes. From 1,001 to 6,000 feet, boil 10 minutes. From 6,001 to 12,000 feet, boil 15 minutes.
Jellying Tests:Temperature Test - The finish temperature of jelly is 220°F or 8°F above the boiling point of water at sea level. For altitudes over 1000 feet, subtract 2 degrees F. For instance, at 1,000 feet of altitude, the jelly is done at 218°F; at 2,000 feet, 216°F, etc.
For an accurate thermometer reading, place the thermometer in a vertical position and read at eye level. The bulb of the thermometer must be completely covered with the jelly but must not touch the bottom or sides of the saucepot. (Remember to test the accuracy of the thermometer by placing it in boiling water.)
Spoon or Sheet Test - Dip a cool metal spoon into the boiling jelly mixture and lift the spoon out of the steam so the syrup runs off the side. When the mixture first starts to boil, the drops will be light and syrupy. As the syrup continues to boil, the drops will become heavier and will drop off the spoon a couple at a time. When the drops form together and "sheet" off the spoon, the jellying point has been reached.
Refrigerator/Freezer Test - Pour a small amount of boiling jelly on a plate, and put it in the freezer for a few minutes. If the mixture gels, it should be done. During this test, the rest of the jelly mixture should be removed from the heat.
When does molting in crayfish occur?
Molting occurs when and because they need to grow. Crayfish have exoskeletons which means they have a hard, protective shell on the outer layer of their body. They need to grow out of their shells to gradually get bigger.
crabs have 8 legs, 2 pincers:
Although crabs come in a variety of shapes and sizes they all have the same general body plan. All crabs have one pair of chelipeds and four pairs of walking legs. Also referred to as claws, nippers or pincers, the chelipeds are the first pair of legs on a crab and their most distinguishing structure. Chelipeds are used for holding and carrying food, digging, cracking open shells and warning off would be attackers. The carapace is the hard cover or exoskeleton which protects the internal organs of the head, thorax and gills.
How long does a blue shell crab stay dormant?
apparently form November to may, what a bummer, i really wanted to throw out a trap soon!
Do land hermit crabs poo and pee?
Hermit crabs do excrete waste, they pee so little, you dont notice it, and they store it in their shells and scoop it out, along with excrement.
How long can a hermit crab be without water?
Hermit crabs live on land, for they only need water to drink, not to live on/in.
Do crab apples come from crabs?
Crab apple trees are members of the Rose Family, they are edible and delicious, they were the only apples around for millions of years until the ancient Turks bred them into domestic apples in the Ili valley of Kazakhstan.

What fish eats a fish that eats plankton?
Yes they do.
Little fish eat phytoplankton because they are the base of the food chain. Small fish eat phytoplankton, medium fish eat small fish, and big fish eat medium fish. Humans (you and me) eat the big fish. That is the phytoplankton cycle.
What are the young ones for crab called?
horgen crab nuggets.
YOFC is a non-profit organization seeking the cessation of crab killing world wide. You must be under 18 to sign up. You must also commit to being a member for at least 50 years and will then be transitioned OOFC (Old Ones for Crab) pronounced oofkah
Do you need to clean a hermit crabs aquarium?
Yes, because the humidity needs to be a bit above average. Also, they sometimes prefer to drink out of a sponge. You need to have the sponge in a ocean-water dish that is deep enough for the hermit crab to submerse in. Thus giving a choice of drinking from the sponge, drinking from the water itself, or soaking in the dish - which helps with molting and gives the crab a natural option for bathing like he would have in the wild. make sure there are always BOTH fresh and salt water dishes in your crab tank - dechlorinated and de-metalled water is vital to your crab's survival! and the salt water should NOT be table salt! you need ocean salt - like oceanic or instant ocean found in pet stores for aquariums. table salt is harmful to hermit crabs.
Can you keep hermit crabs with other animals in the same habitat?
Very few. Because hermit crabs need to remain stationary to molt they need to be kept with their own kind to avoid being cannibalized.
Some owners do add rollie pollie bugs to their crab tanks as cleaners and that has proven to be quiet successful.
Generally, crabs feed on any other small fishes or crustaceans, alive or dead that they can catch. For fishing purposes, we use old, cut-up sections of stinky, dead fish. The odor attracts them to the crab net. Here in Oregon, a particularly vitriolic insult or threat is to call someone "Crab Bait". As in, "OK, nowyou're crab bait." (The threat) And, "Ugh! He looks like crab bait to me." (Not attractive and/or clean) :>)
When is the best time to buy crabs with the yellow stuff in it?
not entirely sure why you would want to buy crabs with poo inside of them but if you like the yellow muck then you would want to catch or buy them either during or right after the mating season.
How can you tell the difference between a land and a marine hermit crab?
You can tell a land hermit crab from a water hermit crab by looking at the claws/arms or legs. If it is a water crab it will be blueish and if land crab it will be pinkish purpleish. If your crab is a water crab don't just throw it in water and leave it there, put a tiny bowl in it's tank or cage that is low to the ground and make sure that the water level is a bit lower than the hermit crabs top of its legs. Also have a wet sponge for each kind of hermit crab in the crabs tank.
