Unknown. Hermit crabs have been on all continents since the Stone Age.
Technically, hermit crabs are still evolving. But their first appearance in the fossil record is in the early cretaceous.
first the hermit crabs mothers lay eggs then the eggs hatch and as soon as the eggs touch salt water, they burst open intobaby hermit crabs. Then they arelarvae. Then they grow in to adults and find a shell to live in.
not if they get eaten first :)
* first they are big and small * up to 6 in.
Hermit crabs lay their eggs in the ocean and the babies live there until around week 6 when they emerge onto dry land and take up their first shell.
They look like cherries that are blue and yellow.
No. They are secondary consumers because they feed on primary consumers

First of all, sand crabs are not hermit crabs. Sand crabs are usually tan, white, brownish, or other flesh-like colors. If you catch one, let it go--They need water.
Hermit crabs communication is very mysterious. We know that they make a clicking and chirping noise, especially when they are agitated. They also wave antennae at each other when they first meet but this could be just "feeling" each other out more than communication. So they do have the means to communicate but we do not know if they actually do it.
