When fight-or-flight instincts kick in, anything is possible, and animals will go to extremes to
survive. After finding itself trapped on a fishing boat, an octopus appears to have no chance for escape, but it somehow manages to push its body, and science, in ways that are seemingly impossible. Later, a 200-pound male orangutan goes above and beyond to save an injured baby bird from drowning
in a pond at a zoo. And when a bear loses her cub, she goes to deadly extremes to reunite with her baby.
