This Beautifully shot documentary delves into the secret world of reproduction in the oceans. All is revealed in this underwater ballet of survival as we focus on the most natural, the most beautiful, the most fascinating (and most dangerous!) of all the urges - sex! Watch complex courtship rituals, invertebrates that impregnate each other, males who give birth, and the largest reproductive event in the animal kingdom, the spawning of the great battier reef. See the unbelievable lengths that doting parents go to, to nurture and to protect their offspring in these nurseries of the deep. Fascinating, colorful and awe inspiring, this is a must-see journey through the oceans.
