A few summers ago, I volunteered at the Marine Mammal Rescue.  There were a lot of baby seals that get stranded on shore.  Usually the mother seal leaves the baby to go hunt for food, but will get spooked off if humans start coming into the area, or the water recedes and they cannot return to their baby.  The Marine Mammal Rescue took in these baby seals to rehabilitate them and release them back in the wild.
