January 1st: ~1

Sea Lion of the Month

SLofMHappy New Year! Since we are at the beginning of a brand new year, I thought we could look back to the beginning of this project. The Sea Lion of the Month for January  is ~1, who was the first pup marked back in 2011. This sea lion is a female that was marked on June 23, 2011 at Gillon Point (on Agattu Island). She weighed about 54 pounds (24 kg) and was almost 3.5 feet (103 cm) long.

She has proven to be quite the home-body, staying around Agattu Island. We have spotted her mostly in remote camera images at both Cape Sabak and her birth place, Gillon Point, on Agattu Island. She stuck around Gillon Point until the spring of 2012 and then she must have gone somewhere with her mother by the time summer came around because we didn’t see her in person or in our remote camera images again until the spring of 2013!

Here is an image of ~1 captured on June 17, 2013. She is about two years old in this image and looks quite cozy snuggled up to a mother-pup pair!

From spring of 2013 through 2014,  she stayed mostly at Cape Sabak with some intermittent visits back to Gillon Point. Below you can see an image we took of ~1 during our visit to Gillon Point on June 23, 2015, exactly 4 years after the day we captured her in 2011. She’s was looking great and as you can see has developed some fungal patches. These fungal patches (circle markings) are harmless and usually permanent which can help us identify her in the future!



We saw her again in 2016 but this time with a pup (no picture taken but the sighting was confirmed)! True to form, this female sea lion must have bred when she was 4 and then had her first pup the following summer when she was 5. Though we didn’t see her in 2017, hopefully you all are seeing her in remote camera images and we will see her next summer with another pup!

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!
