The blue-edge leviathan (Nauta barbatus), also known as the sea goat, is a filter-feeding sea dragon with a cosmopolitan distribution across the oceans of the Sunken Continent. Thousands of leviathans meet at the equator each year for the mating season. Males of the species, known as billies, often joust and ram one another in competition for mates. When gathered in particularly large pods, blue-edge leviathans will flip and bellyflop in and out of the water en masse in a behavior called “pancaking.”
