          This small shark’s eggs are protected within leathery cases                             soon dry out
          called mermaid’s purses. Tendrils anchor the case to
          seaweed to prevent it from being swept away. After months
          of development, during which it is fed by a yolk sac, the
          young dogfish pushes its way out.
