Etereater

Etereaters (エーテルイーター Ēteruītā) are microorganisms in the world of Earth Land that absorb eternano.

Description
Etereaters are microorganisms which reside in various ecosystems in the world. They are described as eterotrophs as they 'eat' the magical particle: eternano. They absorb it from their environment and in large quantities in an organism, are able to cause damage: such as due to overconsumption of the organism's eternano within their body. They have the appearance of large, round heads, eyes, mouths and bodies which are highly disproportionate to their bodies. They also have biotechnological uses, as seen in Nikolai Fleming's Eternano Modulator - absorbing atmospheric eternano and distributing it into his own body in order to increase his own eternano levels.
