@antedeluvian: I seem to remeber someone making the apt suggestion of a shiver of sharks. In my case would work for snakes as well.
A "shiver of sharks" is an "official" one -- they don't use that for snakes although I agree it would be apt (as would a "scream of spiders"). You can have a "knot of snakes" and a "rhumba of rattlesnakes".
