Raised on the rugged plains of Australia, Matt Wright had plenty of jobs -- horse wrangler, Australian Army soldier, crocodile egg collector -- that helped develop his passion and skills for a career as a helicopter pilot and wildlife relocator. Featured in half-hour episodes of "Outback Wrangler," Wright tracks down, captures, and transports a diverse range of dangerous animals, including crocodiles, wild buffalo and even polar bears, that are posing a threat to people. As a chopper pilot he is able to access areas that would otherwise be impossible to reach. Matt's goal, he says, is based on the preservation of wildlife: to remove and relocate problem animals rather than kill them.

Only the strongest survive in the animal kingdom, where the competition for food, territory or mates means employing skillfully crafted tricks of the trade. "Animal Armory" incorporates high-end imagery and computer graphics to reveal how wildlife use their teeth, claws, antlers, camouflage, venom and even spit to threaten and intimidate rivals and predators alike. With weapons of deception, animals disarm and entice prey to their death. Meanwhile, perhaps the oldest weapons employed by animals are projectiles, which have evolved into their own versions of poison-tipped harpoons, chemical missiles and high-powered bullets.

In the varied forms of veterinary medicine, Dr. Susan Kelleher's practice may be one of the more unusual. Known as Dr. K, she runs South Florida's Broward Avian and Exotics Animal Hospital, and this series follows the staff as it cares for rabbits, ferrets, foxes, fish, birds, reptiles, marsupials, and even primates. As do some other vets, Kelleher thinks domesticating wild animals like monkeys is a bad idea, but that feeling doesn't interfere with her taking care of them: "If it will fit through the door, I'll treat it," she says.
