as much as tardigrades get great press, I really prefer rotifers, especially bdelloid rotifers. A few months ago I noticed some nice sludge on a deck chair that was wet, it was full of rotifers (probably 10 for every tardigrade). They are actively hunting, in a way that is much more interesting than watching a tardigrade. A few days later the sludge had dried out to a powder. If I add water to that powder, in 5-10 minutes, tehre are rotifers swimming around, hunting.
