10 Animals That Could Technically Live on Other Planets

7. The Resilient Antarctic Krill

Antarctic krill are small crustaceans that play a critical role in Earth's marine ecosystems, serving as a primary food source for many species. Their ability to survive in the frigid waters of the Southern Ocean suggests they could adapt to the cold environments of icy moons, such as Europa or Enceladus. By forming the base of the food chain, krill could support the development of complex marine ecosystems on these moons, fostering biodiversity and enabling the study of life in extreme conditions.
