In MHFU, there's some science behind where the 2 kinds of Gravios live. The White Gravios (Normal one) lives in the Volcano, and the colour White reflects heat, which is useful in the Volcano. The Black Gravios (Subspecies) lives in the Swamp, which is a colder area. The colour Black absorbs heat, so the Black Gravios can keep warm in the freezing caves of the Swamp.
