This film explores how gene duplications and mutations have led to remarkable physiological adaptations in Antarctic fish.

The discovery of the Antarctic icefish has provided a stunning example of adaptation in an environment that is both hostile and abundant. Scientists Bill Detrich, Christina Cheng, and Art DeVries have pinpointed the genetic changes that enable icefish to thrive without hemoglobin and red blood cells and to avoid freezing in the icy ocean.

The “Abbreviated Film Guide” provides a short summary of the film and key concepts.
