Giant Earth Worm
Believe it or not, the Martiodrilus crassus isn’t the largest earthworm known to man, but these monsters can be found in the Amazon, where the food is readily available and they have the space to grow!
The titan beetle is one of the largest beetles in the world, with the largest reliable measured specimen being 16.7 cm (6.6 in) in length. These huge bugs will hiss if threatened, but they’re not aggressive. The short, curved and sharp mandibles are known to snap pencils in half and cut into human flesh. Adult titan beetles do not feed, searching instead for mates. Titan larvae feed on decaying wood below the ground, then spend just a few weeks as adults. We don’t know much about this particular insect’s biology, but some similar beetles don’t eat in their adult forms.
Titan beetles only live a few weeks.
When the weather is at its hottest and most humid, they fly around looking for mates by following the scent of pheromones, which are airborne chemical attractants produced for mating purposes.
It is known from the rain forests of Venezuela, Colombia, Ecuador, Peru, the Guianas, and north-central Brazil. The titan beetle, like so many creatures, are threatened by the rapid destruction of its rainforest habitat.
These big guys are Whip spiders, also called tailless whip scorpions. I saw one of this up close and personal when we were in Mindo, Ecuador. They're unbelievable to see and don't even look real. They're huge, and very sedate unless threatened. They're common in the Ecuador Amazon.

These spiders are mainly present in Ecuador in the Amazon Region. This climbing species builds its nests primarily in hollows in the trees, sometimes in the vicinity of epiphytic plants. These spiders eat mostly crickets, cockroaches, mealworms, waxworms and darkling beetles, but they also can catch small rodents.
The green anaconda, also known as the common anaconda and water boa, is a non-venomous boa species found in South America. It is the heaviest and one of the longest known extant snake species.
Assassin bugs are easily recognized for their proboscis — the trunk-like organ protruding from their mouths — which they use to inject their poisonous saliva into their prey, melting their organs from the inside out. This makes them dangerous to the other bugs in the Amazon rainforest, even those larger than they are. As for the danger, they pose to humans, the larger ones can deliver a painful bite, while one subfamily — the kissing bugs or cone-nose bugs — can transmit Chagas disease, which results in about 12,500 deaths a year.
