Actor Crab;
Crab = getOneObjectAtOffset(0,0, Crab.class);
if (Crab != null)
    {        
    World world = getWorld();
    world.removeObjects(world.getObjects(null));
    world.addObject(new GameOver(), world.getWidth()/2, world.getHeight()/2);

It all looks okay, so far. Are you getting any errors? If so, what are they, in detail?

Herein lies the problem. You have this (starting line 33) -- "if crab touches middle of crab, then end game." Your enemy is not involved as coded.

It is called "poison" and here is its code:
public class poison extends Actor
{
    public void act() 
    {
        move(4);
        if (Greenfoot.getRandomNumber(100) < 10)
        {
            turn(Greenfoot.getRandomNumber(90) - 45);
        }
            if (getX() <5 || getX() >= getWorld().getWidth() - 5) 
            {
                turn(180);
            }
              if (getY() <= 5 || getY() >= getWorld().getHeight() -5)
              {
                  turn(180);
}
Actor Crab;
Crab = getOneObjectAtOffset(0, 0, Crab.class);
if (Crab != null)
{
    World world;
    world = getWorld();
    world.removeObject(Crab);
    Greenfoot.playSound("eating.wav");
}
}
}

Remove lines 18 thru 26 in poison class. Replace lines 32 thru 34 in Crab class with: 
Actor poison;
poison = getOneObjectAtOffset(0, 0, poison.class);
if (poison != null)
