Thought I would start a thread where we could list "Did you know" facts about garter snakes. It can be a scientific fact or a fun fact (personal opinion)
For scientific facts please list your source.
I'll get things started.

Did you know that during courtship the male garter will use a rippling movement along side the female.
This movement is called caudocephalic waves. (The Garter Snake- Rossman, Ford and Seigel)

Did you know that garter snakes are begging machines.
