On July 2, 2017, at 12:25 a.m., the Marine Mammal Department was thrilled to witness the birth of our newest California sea lion, Ron. Weighing approximately 10 pounds at birth, he spends most of his day nursing and napping next to his amazing mom, Tipper.

He is named after Ron Schusterman, a renowned marine biologist and leading researcher who studied cognition in primates, dolphins, and pinnipeds.

At only 4 weeks old, Ron has really gotten the hang of moving around on his little flippers. He is pretty agile on land, but has yet to figure out the art of swimming. While he definitely shows interest in water, as you can see in this video taken by WCVB Channel 5 Boston, he is only swimming in small spurts. We expect that he will start checking out his underwater world more frequently over the next few weeks … with his mom’s assistance, of course.

In the meantime, he will continue to spend his days relaxing next to his mom, stretching out those flippers, and checking out his environment, including all of his toys, such as the one in this video.
