March 1st: ~35

Sea Lion of the Month

The Sea Lion of the Month for March is ~35. This sea lion was in the first group of sea lions that was marked on Gillon Point (Agattu Island) back in 2011 and has had a pretty adventurous life so far! When this female was marked on June 23, she weighed about 53 pounds (24.2 kg) and was almost 3.5 feet (105 cm) long.

~35 after she was marked on Gillon Point (Agattu Island) on June 23, 2011.


In our records, we only saw ~35 once more on June 23, 2014 and then we never saw her again… Where could she have gone? Well, it turns out, she showed up again in 2016 all the way on Medny Island in the Commander Islands in Russia! This Island group is the next group just west of the Near Islands which is the westernmost part of the United States.

The great news was that when they spotted her at the Medny field camps, she had just birthed a pup! This means she was 5 years old when she had her first pup. She also gave birth to her second pup this past summer of 2017.

~35 spotted in 2016 with her first pup in Russia. You can also see M750, an adult female marked on Medny Island.

This sea lion isn’t the only one to show up in Russia, they also spotted ~141 last summer for about five days on the Medny Island rookery among hundreds of fur seals! Can you see how much smaller fur seals are compared to Steller sea lions?

~141 from Gillon Point (Agattu Island, U.S.) spotted among northern fur seals on Medny Island from July 30 to August 8 in 2017.

Curious about other pinnipeds (seals and sea lions)? Check out our neighbors in the Pacific Islands to the south, the monk seals of the Northwest Hawaiian Islands. The Pacific Island Fisheries Science Center features their own Monk Seal of the Month!

We will share the story of one marked sea lion each month. Be sure to check our Sea Lion of the Month page on the 1st of every month to learn about our featured Steller sear lion. You may nominate a sea lion by submitting their full mark on the Sea Lion of the Month nomination forum. Thank you all for your nominations!
