The scienceticfic name for the vampire crabs is Grapsoidea. However, Vampire crabs is just one of the breeds belongings to the Grapsoidea species.
The one and only place in this whole world whereby vampire crabs can be found is only in sulawasi island indonesia and none other.
The Price of a vampire crab in USD is between 15-40 US dollars depending on where you buy it from.
However that is the price if you are buying them outside Asia continent. If it is within the continent of Asia and to be more specific in South East Asia region, the price per crab is far much cheaper than in the west.
Myself, i bought mine in a retail shop from a neighbourhood area at $6 per crab in Singapore dollars. (around 4.8 USD per crab) I have bought 5 of them. 2 males and 3 females.
The convertsion rate of Singapore and USA dollars is actually very close to each other 1 USD = 1.2 SGD & 1SGD = 0.80USD. That is the current conversation as for now. It is around a difference of 20 cents only.
General Information of Vampire Crabs
In a way you can perhaps say that this vampire crabs breed is rare. First of all it is not in anyplace that can be easily found and secondly it is not a common breed that people have as pet. Thirdly, very little information can be found about them even on the internet. Not even wikipedia has information about them as at present.
This crabs itself is very small in size. It is about half of the size of your thumb only. ( Lenght , Breadth and Height) They are carnivores so feeding them with fish as food will be good enough. Once a day will be sufficient.
You really don't need to change the water everyday for them. Around a week once will be good enough or if you want to make it more frequent then around every 3 days once. What's important is that you must have a very wet sponge in the tank.
Just like other breeds and specifies of crabs, i did gradually discover the common thing about these vampire crabs, which is that crabs are born fighters. Especially and particulally the males. Male crabs loves to fight the most and they are pretty violent and ferocious when they fight.
There is is no mercy ! Weakness cannot be tolerated when they fight. Female crabs on the other hand also do fight but the chances of them fighting with their own gender or opposite gender is not high unlike the males.
These vampire crabs like shade and darkness very much based on my personal observation of them. They are perhaps genernally more active during the night than day. It also appears to me that they have big reactions as they pannick easily.

Matting of Crabs
When mating is of concern, it is done usually during warmmer weather. The male crab will perform a dance or ritual to the female and awaits for the female to respond to his wave of his claws. Should the females wave her claws back at the male it means she is ok to mate with him.
Males will always look for females who are matured enough sexually.
When they are ready to mate, they will get into poisition with the male above the female. The female will be in a position whereby her beneath faces the male. This position is commonly known as double.
They will both remain in this position until the shell of the female is soft enough to mate. Depending on the specifies and breed, some can remain in this position for up to a week.
Once the female is ready to be mated, she will expose 2 holes which is triangular in shape in her abdomen and male will insert into it. Depending of the individuals of the crabs, once mating is ready to be done , the whole stage of the mating process can take up to 5 hours.
When the eggs are produced, they are carried underneath the female crab all the way until they are ready to be hatch.

Coincidently again, this vampire crabs who process the symbol of the vampire on their shell are also purple in color as well. Perhaps due to too much of a coinsidence, they are hence named has vampire crabs.
