Herpetologist Phil De Vries takes us on a journey to discover some of the most dangerous invertebrates on the planet, from the giant centipede of the Amazon to the deadly Japanese mandarin wasp. But beware: what might seem like a nightmare to us is actually something this eccentric scholar can't get enough of.

The North American bullfrog is a voracious carnivore with a seemingly insatiable appetite. It devours virtually anything in its path. In times of need, it will even eat its own kind. These frogs were introduced to the western United States in the early 1900s. Today, with few natural enemies, they are devastating the local ecosystem. Thus began the hunt for the bullfrog.

Predator versus prey in a deadly battle on the African plains. Leopard and warthog: Two unlikely creatures linked by fate on the African savanna. One is predator, the other, prey.

A small but highly efficient killing machine - a hornet two inches long and with a wingspan up to three inches - lurks in the mountains of Japan. The voracious predator has a quarter-inch stinger that pumps out a dose of venom with an enzyme so strong it can dissolve human tissue. Just one of these hornets can kill 40 European honeybees a minute; a handful of the creatures can slaughter 30,000 European honeybees within hours, leaving a trail of severed insect heads and limbs. Someone who is stung by the hornet and doesn't receive proper treatment soon thereafter can die from the venom, which is powerful enough to disintegrate human flesh. About 40 people die each year after being stung by giant hornets, mainly as a result of an allergic reaction to the venom.

From 1968 to 1972, photographer and filmmaker Bob Campbell documented the activities of Dian Fossey as she developed a cross-species bond with Rwandan mountain gorillas. Campbell shot 70,000 feet of film, but only a fraction of his material was edited into the lecture presentation that preceded Fossey's Gorillas in the Mist. This program compiles highlights from the previously unreleased footage, offering an unforgettable glimpse into the gorilla community and Fossey's relationship with it. Her methods may not entirely jibe with those of modern conservationists, but there is no denying the profound impact of her work on current research and eco-activism.
