Nuclear sunscreen poopycell

From 2speccers2tools wiki

This poopycell has lost its symbiosis with the asshole cell. They are now extremophiles which cover almost every surface on the 2s2t planet. They have evolved the ability to absorb radiation and use it as energy, like the radiotrophic fungi of earth. They help reduce the long-term effects of radiation from radfauna, although immediate contact with gamma ray beams is still obviously deadly. Some of these microbes live underwater and some live on land. Most live in forests and jungles but some are adapted to deserts and tundras, however none of them form a thick enough layer to be visible to large fauna, except on the seafloor where they may accumulate as a thin clearish-brown layer.
