Vilesea drift through the surface waters of tropical regions, using their prehensile tail to cling to driftwood or to one another. They absorb sunlight through the leafy fin on their back, sustaining themselves on the energy of the tropical sun.

By cleverly flicking the fins on its back side to side, it moves in any direction while facing forward. In seasons when it produces more pollen, the air around a Vilesea turns yellow with the powder as it walks.
