Pond snails in 5-gallon aquarium having sex. Apparently they are hermaphroditic and are able to f..., er, fertilize and get fertilized, or do it to themselves, though in the latter case the eggs are clones. In terms of ancient Greek grammar, they are active, passive and middle at the same time! Occasionally I've observed in-line triads as well. Observed them stay connected for 13 minutes, then the egg sac(s) appears within 3 days. August 23, 2011.
Throw in a front double biceps and this video is a "favorite"!
