Fire whales are native to the Plane of Fire, and can still be found living there. However, their ability to freely move between the Elemental Planes and the Material Plane has allowed fire whales to spread to numerous other habitats. Fire whales on the Material Plane often inhabit the hearts of volcanoes, while others live in ocean abysses where they rely on their ability to boil away water that comes into contact with their bodies to protect themselves from the immense cold of the deep ocean.
