The Tak Tak are a race from the Delta Quadrant.
They communicate includes ritualistic gestures as well as speech.
The Federation made first contact with the Tak Tak in
2373. The U.S.S. Voyager led first contact. Captain Kathryn
Janeway offended the Tak Tak by placing her hands on her hips. Neelix had
to work very hard to deal with the situation.
The Tak Tak had no cure for the Macrovirus and had a
policy of "purifying" any infected ship or colony. They destroyed an
infected Garan mining colony in 2373 and also targeted Voyager for the same
reasons.
