Species Name:
Acidium Vorax

(Latin, I am so creative!)

Other:
With such scarce food and harsh conditions upon this icy planet, one has to be extremely competitive for food. As such, finding viable long-term sources of food is difficult. So, what is the natural evolutionary answer? Evolve to eat more. While still small and harmless, this organism contains within it, a fairly powerful acid that can break down most things and use the chemical reactions created from breaking down said things, for energy.
