S19E16 Australia's Little Assassins

When animals are the subject, most people associate Australia with lovable koalas and leaping kangaroos. But an even more distinctive aspect of Australian wildlife is its abundance of animals -- from snakes and spiders to a host of marine life forms and at least one mammal -- that use venom to defend themselves, attack prey, and in some cases help digest food.

S24E13 9.5

Crime Scene Creatures

They are among the most reliable witnesses to a crime — expert in their testimony and bulletproof in their account. Yet they never utter a single word. They are the animals, plants, and insects that are being recruited by a special breed of forensic scientists to solve the most seemingly impenetrable of crimes.
