To escape the mongoose.
Yes, they dig burrows with their powerful front claws.
Well crabs lay eggs in the sea most the time but some types of crab lay egg in there and they mat in it as well
To stay warm and safe. Under ground is warmer and most animals can not get to them but some can dig up the burrows. - I hope this helps
you can put sand or stones in a crabs habitat my fiddler crab enjoys hiding under rocks and other things that he can fit into he will go into and space he can to hide so you can put large stones in for them to hide under. i bought a smalldome kind of thing that has a bottem layer then stones on either side to hold a large piece on top of it so he likes to go in there cuz he can sit in the water. also you can buy them beds at the pet store they like those. but all crabs need water so put water in it some crabs need salt water and some need normal water and mine needs part salt and part clean. so i hope this helps :)
