Those who've followed this blog since it's conception might remember my philosophical-phylogenetic musings on Copella arnoldi, the jumping spawners (complete with hand-drawn illustrations!) If you've missed that article, you might want to read it - frankly because I marvel at how much time I must have spent on it! ;)
In any case, finally you can see the actual footage that inspired me to write that treatise! So I guess interested readers of the original post can now just skip the explanation part altogether and move on to the musings.
The snippet is from a documentary entitled Equator: Rivers of The Sun. Do watch, it's amazing.
