"The Amazon Rainforest is the largest rainforest in the world. It covers 40% of the South American continent and can be found within the following countries: Peru, Ecuador, Columbia, Venezuela, Brazil, Bolivia, Guyana, Suriname as well as in French Guiana. The Amazon Rainforest is home to 427 mammal species, 1,300 bird species, 378 species of reptiles, and more than 400 species of amphibians. Some of the animals that live in the Amazon Rainforest include jaguars, sloths, river dolphins, macaws, anacondas, glass frogs, and poison dart frogs. One in ten known species in the world lives in the Amazon Rainforest as do one in five known bird species.

The Capybara is similar in appearance to cavies and guinea pigs. Barrel-shaped and covered in dark red and brown fur, adult capybaras stand around 2 feet tall at the shoulders on all fours, are in excess of 4 feet long, and may weigh close to 150 pounds, making them massive for rodents. Semi-aquatic rodents by nature, they make themselves quite at home amidst the Amazonian wetlands.

The Giant Anteater, as their name implies, this variety of sloths loves to chow down on bugs, including ants. In fact, their tubular snouts and long tongues are especially well-suited for gorging upon insects practically wherever they may be. These creatures carry the “Giant” moniker as they are much larger than other anteaters, reaching over 7 feet in length. Also unique among anteaters and sloths in general, Giant Anteaters prefer to stay out of the trees and stick to the rainforest floor to roam in search of their next insectivorous meal. "

"Congo River, formerly Zaire River, river in west-central Africa. With a length of 2,900 miles (4,700 km), it is the continent’s second longest river, after the Nile. It rises in the highlands of northeastern Zambia between Lakes Tanganyika and Nyasa (Malawi) as the Chambeshi River at an elevation of 5,760 feet (1,760 metres) above sea level and at a distance of about 430 miles (700 km) from the Indian Ocean. Its course then takes the form of a giant counterclockwise arc, flowing to the northwest, west, and southwest before draining into the Atlantic Ocean at Banana (Banane) in the Democratic Republic of the Congo. Its drainage basin, covering an area of 1,335,000 square miles (3,457,000 square km), takes in almost the entire territory of that country, as well as most of the Republic of the Congo, the Central African Republic, eastern Zambia, and northern Angola and parts of Cameroon and Tanzania."

"The Congo rainforest is the second-largest rainforest in the world. The forest is home to some of the richest biodiversity on the planet, with thousands of fish, plant, bird and mammal species.

According to the World Wildlife Fund, there are 400 species of mammals, 700 species of fish and over 1,000 species of birds found in the Congo rainforest alone. Some of the area's most famous occupants include leopards, forest elephants, gorillas, chimpanzees, lions, hippos, cheetahs, giraffes, spotted hyenas, bonobos and, of course, lowland and mountain gorillas. Many of these animals are endangered, and conservation efforts have steadily gained momentum over the years. "

"Gorillas are the largest species of primates. The males are often twice as big as the females. The males grow to around 5 ½ feet tall and weigh around 400 pounds. The females grow to 4 ½ feet tall and weigh around 200 pounds.

Gorillas have long arms, even longer than their legs! They use their long arms to "knuckle-walk". This is where they use the knuckles on their hands to walk on all fours."

The Nile River is considered to be the lifeline of Egypt. Without the Nile, much of Egypt would be unliveable. The river is home to many species of aquatic fauna and also supports hundreds of other terrestrial species that live along its banks. Many of the animals living in and around the Nile are feared and revered by local human residents. Ancient Egyptians would even worship some of them." Animals in the Nile River include Crocodiles, Hippopotamus, and Tiger Fish.

"Hippopotamus are considered the third largest mammal that lives on Earth, only behind the rhinoceros and the elephant.

Hippos have short legs, a huge mouth, and bodies that are shaped like barrels. Although they look extremely fat, hippos are actually in excellent shape and can easily outrun a human."

Crocodiles—reptiles as fierce as Tyrannosaurus rex and almost as ancient—have prowled waterways for millennia. The Nile crocodile reigns as one of the most feared reptiles on the planet and is capable of taking down a small hippo or a hulking African buffalo.

"Since 1997, more than 2,216 new species were discovered in the Greater Mekong subregion, with 139 new species identified in 2014 alone, including a color-changing frog, a zombie-making "dementor" wasp, and the second-longest insect in the world.

The region is home to numerous endangered species, including the Indochinese tiger, the Asian elephant, the Irrawaddy dolphin, and the Mekong giant catfish. In particular, the Greater Mekong region is rich in endemic species, including the saola, one of the world’s rarest mammals."

"Irrawaddy dolphins are found in coastal areas in South and Southeast Asia, and in three rivers: the Ayeyarwady (Myanmar), the Mahakam (Indonesian Borneo) and the Mekong. The Mekong River Irrawaddy dolphins inhabit a 118-mile stretch of the river between Cambodia and Lao PDR and are scarce—just 92 individuals are estimated to still exist. These dolphins have a bulging forehead, short beak, and 12-19 teeth on each side of both jaws."

"Saola (pronounced: sow-la) are recognized by two parallel horns with sharp ends, which can reach 20 inches in length and are found on both males and females. Meaning “spindle horns” in Vietnamese, they are a cousin of cattle but resemble an antelope."
