Vorcha

The vorcha are a race featured in Mass Effect 2, the forthcoming sequel to Mass Effect.

Overview
The vorcha originate from a small and overcrowded planet which has been largely stripped of natural resources by successive generations of this fast-breeding species. The lack of resources has resulted in a tight-knit clan based society in which rival clans wage constant war against one another for control of scarce resources. This constant warfare has had the twin effects of making each generation of vorcha stronger and more aggressive than it's predecessor, while keeping their society extremely primitive.

Biology
The vorcha are the most short-lived species currently known, with an average lifespan of only 20 years. The vorcha are known for a rather unique biology that differentiates them from other known species and which carries with it a striking set of advantages and disadvantages. The vorcha have clusters of non-differentiated cells, similar to those found on |the Planarian worm
