Anyone who has ever worked in a controlled environment like a zoo with venomous snakes knows that the possibility of a venomous snake bite is serious business. Protocol including alarms and lock down procedures are common place. The right snake, the wrong timing and fangs meeting flesh merits an emergency situation and the entire facility jumps into action. Yet, there are individuals who keep deadly snakes in situations without any backup. Are they thrill-seekers or just naive? Henry Rollins meets people obsessed with dangerous snakes in “Fatal Obsession” the first episode of Animal Underworld and looks into this very question. Crazy or not, if someone is bitten by a deadly snake with no one for miles around, what really happens? It all depends on the venom.

Predominantly slow-moving, energy-conserving koalas are not exactly well-equipped to handle speeding traffic and packs of dogs, or the consequences of encroaching urbanization around Brisbane, Australia. Their once quiet lives are now filled with social pressure, conflict, disease, overcrowding and the external stresses of living in the middle of what amounts to an alien world.The film explores the day-to-day dramas of urban koalas, seen through the eyes of the scientists studying their every move and vocalization. Fascinating social dynamics include a mother raising her baby, territorial displays and vicious fighting by males competing for mating rights, and the surprising life and loves of "traveling salesmen," rogue males who truly play the field. New science even "cracks the koala communication code," providing insights into their basic language and social structure. Their thunderous roars are difficult to reconcile with the familiar perception of them as cuddly creatures, yet there is a great deal about them that is surprising. Viewers will get a whole new perspective after watching this film.
