To see their surroundings and most probably to find a mate
It has two eyes:)
purple ones
not real sure..
The stalk of the crabs eyes if cut off or got eaten, the crab is able to grow one back same to the crab's eyes.
The eyes would be located somewhere on the horseshoe crab.
crabs are scavengers in the wild. I am assuming it is a hermit crab you are asking about. There are a number of crab foods you can find at your local petstore.
Eyes on stalks, a hard shell covering the back and other limbs, two front-positioned claws, 6 (?) legs.
it depends on the size of the crab
To look out for predators.
The crayfish's eyes can move and most of the time , it is to protect the eyes so it moves into a "case".
i dont know.How does a red rock crab use its nippers?
You have to get the crab pot for the sailer then he will give you the containtens [a crab] you can use the crab as a crank.
