Snapping Behavior of the Shrimp Alpheus californiensis

A pair of very smooth disks, located on the claw of the snapping shrimp Alpheus californiensis, are temporarily held together by cohesive forces of water. This allows the closer muscle of the claw to generate a large amount of tension before these cohesive forces are overcome, and results in a rapid closing movement.
