Green Iguana
Most adult Green iguanas (Iguana iguana) reach lengths between 4-7 feet (1.2-2.1 m). Their coloration ranges from dull gray to bright green. They are found over a large area from Mexico to southern Brazil and Paraguay as well as in the Caribbean. They are omnivores and the majority of their diet is plants and fruits. Green iguanas are threatened by habitat destruction and the pet industry.

Silver arowana
The Silver arowana (Osteoglossum bicirrhosum) is silvery in color with red, blue and green highlights that develop with age. They can grow to 4 feet (1.2 m) in length but generally range from 2½-3 feet (.8-.9 m). The male and female are hard to distinguish but the anal fin of the male is larger. They are carnivores, eating almost anything that will fit into their mouths. They can leap up to 3 feet (.9 m) into the air to catch insects. The Silver arowana is found in the Amazon River flood plains and is not endangered.

Ornate horned frog
The Ornate horned frog (Ceratophrys ornata) is a round, plump amphibian that grows up to 6 inches (15 cm) in length. The females are slightly larger than males. Their mouth appears to extend around the entire body, giving them the nickname "Pac-man" frogs. They are native to South America, where they burrow in leafy, muddy vegetation of tropical forest floors. Ornate horned frogs eat insects, lizards, mice and other frogs.

Caecilians
Caecilians are worm-like creatures that are actually amphibians. Typhlonectes natans is the only species to be mostly aquatic. Other species burrow in the soft soil of the Amazon River basin. They can reach lengths of 18-22 inches (46-56 cm).

Amazon yellow-spotted river turtle
Yellow-spotted Amazon River turtles (Podocnemis unifilis) have a shell length of 27 inches (68 cm) in females and 14 inches (35 cm) in males. The carapace is brown to greenish-gray with a narrow yellow border that darkens to olive gray with age. One barbel is present on the chin in the Orinoco population and two in the Amazon population. The Yellow-spotted Amazon river turtle is found in lakes, ponds, floodplains and lagoons along the Orinoco and Amazon Rivers.

Freshwater stingray
Freshwater stingrays (Potamotrygon spp.) live in the shallows of South American rivers. They spend most of the day resting along the bottom. Their body is a large, round disk marked with circular lines or spots. The slender tail is armed with a serrated, stinging spine that produces venom that is absorbed into the victim's wound. The body of an average adult freshwater stingray is 12 inches (30.5 cm) in length with a tail that can reach 8 inches (20.3 cm).

Electric eel
The Electric eel (Electrophorus electricus) is actually a fish that can reach 9 feet (2.7 m) in length and weigh more than 50 pounds (23 kg). The electricity comes from nerve ending cells in the tail that can produce from 600-1,000 volts at one time (enough to stun a human or a large animal such as a horse). Electric eels have 200-250 "electric" cells per centimeter. They breathe air, coming to the surface to gulp air, which is absorbed by its body. They are native to South American rivers.
