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.

What is the salinity in the water that the crab live?
The salinity affects the crabs by altering the size of their internal organs, causing them to swell and decrease, as the salinity does.
This drastic change in the crabs can cause death, and colour changes within the crab.

What are the uses of the horseshoe crab?
I know of no nutritional use, edible (culinary)or otherwise (medicinal), to humans. I do know that each year the horseshoe crabs comes up on beaches to lay thousands of eggs and these eggs and resulting newborn baby crabs provide numerous birds, water fowl and other sea creatures with nutritious meals. Also, as crabs are scavengers, they keep the ocean bottom clean.

How do you get your pet hermit crab to switch shells?
First of all, you should make sure it actually needs to change shells because it has become too big for it.
To make your hermit crab switch shells, place ONE crab in a small container that the cannot escape out of, put a shell in the container that you would like them to switch into. Turn off all the lights, and have a dark quiet room for them to switch in. Peek on your crab every hour.
Well in the cage you should have more than three shells so whenever it grows it can just change when it wants to.The crab will change when it wants to, when it grows bigger it should change when it cant fit in that shell anymore. Make sure that the shells you put in the cage are bigger than its old one.
Can fiddler crabs climb trees?
In their natural habitat amongst the mangroves they do eat some fruits that fall on to the mud.
How do you find a hermit crab if its lost URGENT?
if its lost but you think its still in the tank, they love to dig and it is somewhere in the floor of your tank. hermit crabs are escape artists, so if you have a branch at the top of the tank, it would climb up and fall out the edge. if its lost and is not in the tank, theres not really much to do except watch the floor carefully and put a lid on the top of the tank so it doesnt happen again, or the crab could just be in another shell.
first of all, there should already be a lid on the cage so you wouldn't have this problem! but, if the hermit crab got out, i would suggest closing the door to the room so it stays in the room and put food on the floor. if the crab has a favorite type of food, that would be better to put on the floor. if that doesnt work, start up a search party and find that little sucker! good luck.
I lost mine 3 times in one day. We looked everywhere. They are nocturnal so we turned off the lights in one room and waited. The crab finally came to the dark room and we found it. If this dosent work put food (tuna or peanut butter) on foil and if the crab goes to get food you will hear it on the foil.

How does the pollution in the bay effect blue crab?
The Blue Crab "breathes" the water, and the more polluted it gets, the more it is like putting toxic chemicals in our air. It also eats the algae, small worms, and other bay inhabitants that also"breathe" the water. the more of them die off, the less and less food there is.
How can you tell the sex of a blue crab?
If you look on the rear part of the underside of a crab it has a kind of flap. In the male (jack) this flap is narrow like a "v" shape in the case of a female (jenny) it is wide and more like the shape of a "U".
yes, fiddler crabs do lay eggs, because they are not mammals and i've never heard of a crab having live babies!
Not all birds. Only sea birds such as seagulls. Seagulls would eat the bigger ones, and smaller shorebirds eat sandcrabs and other crustacians under the sand.
