[Undertoad]

The eggs of horseshoe crabs aren't attended by the parents. Instead, they are simply deposited in the sand by the female as she drags the male along behind her to fertilize the eggs. The male hangs onto the back of the females shell with his claws and is usually about two-thirds the size of the female. Being this much smaller, he provides little resistance as he is dragged around the sand by the egg-depositing female.
