The Southern Gillfin has adapted to life in the colder waters of the southern oceans. Their bodies have plumped up, to provide them with better insulation. Their necks have also shrunk considerably. They reproduce twice a year, mating in large congregations. once the eggs are fertilized, the females will lay their eggs either onto the tail of another or will lay their eggs directly into the water and then 'catch' them with their tail. The eggs will stay their for about a month and a half, before they hatch and move out on their own. The young are fully grown after 2 years, and they can live to be 35–42 years old. They are so successful, they have not only replaced their ancestors, but they have out competed all Islandball Gillfin in their overlapping territory, though the Scuttleball Gillfin has managed to survive.
