Sharks have the ability to blink but since they live in the water they have no real need to moisturize their eyes, so no, they do not blink.
Sharks never stop swimming, if they do they will die, swimming allows their gills to intake the small amounts of oxygen in one water space as they continue moving.
Sharks can have 100 babies at one time in what is called a 'mermaid's purse' which substitutes as a womb for the baby sharks to grow and gain nutrients.
