A Giant 5 Metre Anaconda Leads To Nature's Creepiest Discovery | Expedition Guyana | BBC Earth (Level 1)

George and Gordon are in Guyana. They are looking for big animals. A man on their boat sees a giant snake. It is an anaconda. The snake is 5 meters long. Its body is as big as a car tire. Gordon gets close. He cuts some plants to see the snake. He says it is huge. Anacondas eat big animals. This one is sleeping. Its tongue is inside, so it does not smell them. They leave it alone. Then they see a very big tree. It is a silk cottonwood. Its roots are huge. Later, they find a moth with a fungus. The fungus grows inside the moth. It makes the moth go high. When the moth dies, the fungus spreads. This looks like something from a scary movie. George thinks the fungus might be new to science.
