The screenslime has become much bigger due to no competition in its niche. It has become a little more complex, as the outer cells absorb radiation more and the bottom cells absorb nutrients and water more. They are commonly found growing on the ground or low on trees like moss. They also contain agar which makes them somewhat firm but jelly-like. Like their ancestor they still release tiny asexual spores to reproduce.
