The Seals of Sable Island
Season 18
Episode 2
Each winter, Sable Island transforms into the planet’s largest gray seal breeding colony. The Canadian government has studied this seal population since the 1960s, and now experts from the U.S. are conducting a unique physiological study on mom and pup pairs to better understand how iron transferred during lactation influences a pup’s survival.
