This film records stages of embryonic development of Potosi Pupfish, (Cyprinodon alvarezi), that are extinct in the wild.
A tiny fish might not mean much to us, but it does to the ecosystem it supports, as well as serving as a microcosm for the state of our world.
"A human being is part of a whole called by us "Universe", a part limited in space and time. He experiences himself, his thoughts and feelings, as something separate from the rest - a kind of optical delusion of his consciousness. This delusion is a kind of prison to us, restricting us to our personal desires and to affection for a few persons nearest to us. Our task must be to free ourselves from the prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty. We shall require a substantially new manner of thinking if mankind is to survive."
