Metallic-based Species

Metallic-based life is based on molecular structures dominated by metallic elements. They can be alkaline metals like sodium and potassium; alkaline earth metals like magnesium and calcium; transition metals like titanium, manganese, iron, zinc, copper, silver, platinum, zirconium, etc.; or post-transition metals such as aluminum, tin and lead. Not to be confused with robots, which are manufactured beings, these species on the other hand are naturally occurring.
