The Goliath Seal is a massive pinniped inhabiting the oceans near Arcadia and Vogelheim. Similar to Earth's Sea Lions, these massive, aquatic predators move on land to rear their young. They are able to crawl out of the water with the use of their muscular forelimbs.

Their main diet consists of fish and squid, but they have been known to attack smaller oceanic drakes as well. It is theorized that their massive size is a response to predation from larger drake species.
