Sebastian, or "Sebo", came to live at Atlantis after his home was destroyed by Hurricane Katrina. He is almost 22 years old, is the oldest (but not largest!) sea lion at Atlantis, and weighs around 570 pounds. His daily diet includes a mix of nutritious fish - capelin, herring, and squid β but he LOVES ice cubes for a treat! This Fatherβs Day will be his first year as a Dad! Sebo has fathered two pups, Zemi and Karaya, both born in June 2021.
