Segments in this Video

Deathstalker Scorpion (05:30)


A deathstalker's pincers and tail carry neurotoxins that disables prey and discourages predators. An individual stalks a camel spider, locating striking distance by detecting vibrations.

Komodo Dragons (02:35)

Komodos have a weak bite, but their saliva carries lethal toxins that slowly kills their victims. The poison lowers blood pressure, causing massive internal bleeding and death.

Army Ants (03:33)

These ants kill more animals in the Amazon rainforest than any other predator. A colony embarks on a search for food; scouts, workers, and soldiers create trails. The ants use venom to subdue large insects before subjecting them to dismemberment.

Bullet Ants (02:32)

These ants eat aphid secretions and defend their food source by spewing venom at potential predators. A mother brown bear teaching her cubs how to forage for insects is deterred by the formic acid spray.

Stingrays (02:36)

Stingrays use their stingers solely for protection; pain inducing toxins are stored in underside glands. The barb is deadly, leaving deep lacerations and piercing organs. While hunting, stingrays use camouflage to ambush prey.

Chinese Green Tree Viper (03:39)

Viper fangs are loaded with venom that is stored in sacs. Hemotoxins cause extreme bleeding, pain, and quick death. An individual hunts a mouse, using camouflage and stealth; it swallows its prey whole.

Slow Loris (02:25)

The primate's bite is venomous and its acute night vision can spot prey within 50 meters; the venom is also a deterrent to predators. A female stalks an insect and injects toxins before consuming the prey.

Tree Nymph Caterpillars (05:11)

The caterpillars eat toxic dogbane leaves; the more they consume, the more poisonous they become to predators. After metamorphosis, a butterfly emerges from its chrysalis and flies into an orb-weaver web; it is still noxious and the spider sets it free.

Toxic Vegetation (04:53)

Acacia trees become toxic when eaten, releasing ethylene to warn other trees to increase poison production. The defense mechanism allows animals to consume enough for survival. Pitcher plants lure insects with nectar, digesting them in enzyme reservoirs.

King Cobras (02:59)

Cobras use fixed fangs to pump venom into victims; they can inject enough to kill an elephant. An individual uses acute eyesight and taste to detect prey. The cobra attacks another snake, paralyzing it and swallowing it whole.

Yellow-lipped Sea Krait (05:48)

The snake's neurotoxin instantly immobilizes victims; the semiaquatic reptile hunts for eels. During mating season, a male attempts to breed with an unwilling female; they are immune to each other's bite, and she must wrestle him off.

Clownfish (03:57)

Born immune to sea anemone poison, clownfish live among their tentacles, maintaining a symbiotic relationship. A couple prepares a nursery site, and the female lays her eggs; the male fertilizes them and cares for them as they grow. Hear an episode summary.

Many animals have evolved chemicals to enhance their chance of survival: some scorpions literally drug their potential mates, others use their poisons to defend or to kill. The world of venoms and poisons, the apparatus designed to deliver them, and the strategies that animals employ to use them most effectively is a rich and varied example of natural selection and evolution in action.
