Thresher maw  From ImperialWiki Jump to: navigation, search
Thresher Maw  A thresher maw is an enormous subterranean worm
native to the planet Tuchanka in Mass Effect.  Thresher maws
were somehow distributed to other planets when the krogan race
was given interstellar spaceflight technology to fight in the
Rachni War. They have since become dangerous pests on many
worlds.   Thresher maws can grow to hundreds of meters in
length, and their thick carapaces are difficult to damage. They
are fast burrowers, and they can spit acidic slime.  Personal
