For this #marinefactoftheweek we take a look at a whale journey that just might surprise you!
Did you know that gray whales can undertake the longest migrations of any mammal?
Some of the longest round trips between breeding and feeding grounds can reach up to 20,000 km in distance, or a 10,000 km trip twice a year. That is an extraordinary feat!
However, on the contrary, some whales actually decide not to migrate; in the eastern gray whale population (Bering and Chuchki Seas, Canada and U.S. North Pacific coasts), it is believed that, per year, about 0.5% of the population do not leave for breeding sites.
Do you have more interesting facts on the gray whale?
