crabs eat baby shrimp and other fish such as clown fish. shrimp eat plankton and other single celled organisms.
What kind of symbiotic relationship do the giant anemone and an anemone crab have?
When a sea snail dies, its shell eventually washes up on shore, where the hermit crab uses it as its new home. Therefore this would be commensalism, however since the snail already died there is no living symbiosis.
Can female hermit crabs die in giving birth?
you do not take care ofyour hermit crabs cause i had one and it didn't last long sssooo take care of them cause if you don't they might not be adopted so go and look at them. Their young or the young in the tank...No.Females drop all their eggs into the ocean and the egg hatches and develops over time and then when the crab is ready he climbs onto land and lives there.
How does crab survive in water?
Crabs actually breath in water much like fish. When they go to shores, they take sea water with them in their tiny lungs to breath oxygen from it. However, they must return back to water before the oxygen is over; otherwise, they suffocate and die.
What type of skeleton does a crab have and how does it help the crab?
An Exoskeleton - external skeleton. Stops it getting omnomed
1) Ocean crabs for eating are generally gathered with traps left on the ocean floor.
2) The body louse that is loosely called a 'crab' or referred to as 'having the crabs' are 'gotten from intimate contact with someone who already has crabs." One good method of protection is to bathe frequently, especially after intimate contact with someone else.
What is the best way to cook frozen steaks?
DO NOT COOK FROM FROZEN!!!!!!!!!!!!!!! Let them defrost. You are just asking for food poisoning if you try it. I personally fry steaks on super hot heat to seal the meat. I like them nice and rare inside so I cook them really hot so the outside is cooked properly and the inside is nice and pink. Do it for about 3 minutes or so on each side. If you prefer it a little less bloody then turn the heat down to about halfway, and do 'em for about 4-5 minutes or so on each side. You can tell if they are well done by sticking a fork in and seeing if the juices run clear. Before I cook a steak, I like to tenderize them with a tenderizer (like a small hammer with little points on it). Makes them a little less tough if they are a cheaper cut and helps me get out my frustrations for the week!
Why does a crab has eyes on stalks?
The fiddler crab has stalked eyes because it helps to see around it more. The eyes are above the crab instead of being just in front of it, so if a predator comes around, it might have more of a chance of getting away

Is your hermit the crab dead if his whole body came out of his shell and nothing inside?
Hermit crabs will sometimes come out of their shells under their own free will. However, if you pick up the crab'ss shell and it falls out easily, it is dead. When still alive, the crab will hold onto the inside of the shell.

I found this on the "Louisiana Foods Seafood Distributer" website. "Cormorants are a well known pesky crawfish predator, but now there is another critter out there feasting on crawfish: raccoons. The number of raccoons in southern Louisiana apparently has skyrocketed over the last decade, ever since the region's fur industry went bust. The masked menaces turn over crawfish traps in shallow ponds and even haul up the lines attached to traps in deeper waters to eat both bait and crawdads." Homo Sapiens eat crawdads.
I strongly don't suggest feeding your hermit crab BACON!
Because:
- The salt (unless you buy sea salted bacon i guess) can kill your crab!
- Don't you want more delicious bacon for yourself?
Do red clawed crab need saltwater?
All hermit crabs love sea salt. DO NOT GIVE IT TABLE SALT. IT WILL KILL THE HERMIT CRAB. All hermit crabs should have a small bowl of fresh water & salt water. You can purchase salt water from your local pet store. If you want fresh water you should give your hermit crab bottled water. Faucet water contains toxins which are bad for any pet. They will not die, but it's better to be safe than sorry.
i have read about sharks and i think it would be the nurse shark.
Horseshoe crabs require a steady supply of oxygen to stay alive. Their blood contains a molecule call hemocyanin which carries oxygen throughout the crabs body. Hemocyanin is very similar to the hemoglobin that human blood uses to carry oxygen and that gives our blood it's red color. The main difference between these two molecules is that hemoglobin is an iron-based molecule whereas hemocyanin is based on copper.
Oxygen is transferred from the outside environment to the inside of the body through gills. Very small animals can obtain oxygen directly through the body wall because they are small enough that they don't require much oxygen and the amount of material in their bodies that require it is relatively small. As an animal gets larger it's volume increases exponentially and there isn't enough outside surface area for oxygen to get in. The way large animals deal with this is by increasing the surface area where oxygen comes into the body. It folds. We have lungs which have branches and aveoli which give us an effective surface area of some 2000 square feet. Horseshoe crabs use a system that is also employed by their closest relatives, spiders and scorpions. They use book gills.
Book gills are a fairly straightforward design for getting a lot of surface area exposed to the outside environment in as little space as possible. Imagine a paperback book of several hundred pages in your hand. It might only be an inch or so thick and perhaps 4 by 6 inches tall and wide. Imagine cutting the pages out of the book and laying them side by side. Very quickly you would see just how much print area even a small book represents. Book gills are of a very similar design and each "page" or lamella is a thin double-walled chamber full of blood which can exchange oxygen and carbon dioxide with the outside water. By keeping the gills in motion the crab moves water and oxygen over them and also moves blood through the lamellae. In addition, young horseshoe crabs can propel themselves by using their gills as paddles.
