Horseshoes is an outdoor game played between two people (or two teams of two people) using four horseshoes and two throwing targets (stakes) set in a lawn or sandbox area. The game is played by the players alternating turns tossing horseshoes at stakes in the ground, which are traditionally placed 40 feet (12 m) apart. Modern games use a more stylized U-shaped bar, about twice the size of an actual horseshoe.
Horseshoe crabs have a total of 10 eyes used for finding mates and sensing light. The most obvious eyes are the 2 lateral compound eyes. These are used for finding mates during the spawning season. Each compound eye has about 1,000 receptors or ommatidia.
