Hoatzin

The alternative name of "stinkbird" is derived from the bird's foul odour, which is caused by the fermentation of food in its digestive system. The hoatzin is pheasant-sized, with a total length of 65 centimetres (26 in), and a long neck and small head. It has an unfeathered blue face with maroon eyes, and its head is topped by a spiky, rufous crest. The hoatzin is an herbivore, eating leaves and fruit, and has an unusual digestive system with an enlarged crop used for fermentation of vegetable matter, in a manner broadly analogous to the digestive system of mammalian ruminants.
This is a noisy species, with a variety of hoarse calls, including groans, croaks, hisses and grunts.These calls are often associated with body movements, such as wing spreading.

Howler monkey

Blue poison dart frog

The black spots are unique to each frog, enabling individuals to be identified. This species of frog has a distinctive hunch-backed posture.The glands of poisonous alkaloids located a defense mechanism to potential predators. These poisons paralyze and sometimes kill the predator.

Paraponera clavata

The best known name is the Venezuelan hormiga veinticuatro (the "24 ant" or "24-hour ant"), referring to the full day of pain that follows being stung; it can also refer to the time it takes to kill a human. 

South American jaguar

Anaconda

The world's largest, heaviest, and most powerful snake may also be its most famed. The Anaconda can grow as long as 30 feet and weigh up to 550 pounds! They constantly grow throughout their entire lifetime, eating about 40 pounds of prey every day as small meals. Larger meals that they swallow whole can satisfy them for a few weeks. A female anaconda is typically larger and gives birth to live young which count 20 to 40 little anacondas that are each 2 feet long!
