The Back Story
Depending on the species, a female seal takes care of her baby, called a pup, from 4 days to a year. Staying close to the mother, a pup spends its days sleeping, nursing, and swimming in shallow water.
Scientists are tracking a decline in the number of seals in the far north of Alaska. Changes in fish and whale populations brought on by humans, such as whaling and fisheries operations are thought to be the primary cause.
