The female crab lays the eggs, and not the male.
A male hermit crab is called a geomanta
They need them to fight
A female crab typically needs to mate with a male fiddler crab to fertilize her eggs before laying them. Fiddler crabs engage in a courtship display where males use their enlarged claw to attract females. After mating, the female will lay her fertilized eggs in a suitable environment, often in the water. Without mating, the eggs will remain unfertilized and cannot develop into offspring.
Male
The male has a big claw and the female doesn't
male frogs will croak to attract female frogs.

i dont think the male would eat the female unless they didnt have enuff food to eat
Does a male human have ovaries? No. Roe are not ovaries. Whereas a female crab's roe is composed of her eggs, a male crab's roe is his sperm. This is why male and female roe have different taste and consistency. If male crabs did not have roe, crabs would not be able to reproduce, and they would die out.
If you tip your hermit crab almost upside down, they will come out of their shell a little bit. If the hermit crab is a female, then they will have two little dots on each side of their insides, used for laying the eggs of the hermit crabs. If it is a male you will not find these dots.
