The South American tapir (Tapirus terrestris) it is the largest mammal in South America. It is dark brown, paler in the face, and has a low, erect crest running from the crown down the back of the neck. The round, dark ears have distinctive white edges. Newborn tapirs have a dark brown coat, with small white spots and stripes along the body. The South American tapir can attain a body length of 2 to 2.5 m (6.7 to 8.2 ft) with a 5 to 10 cm (2.0 to 3.9 in) short stubby tail and an average weight around 225 kg (496 lb). Adult weight has been reported ranging from 150 to 320 kilograms (330 to 710 lb).
The South American tapir can be found near water in the Amazon Rainforest and River Basin in South America, east of the Andes. Its range stretches from Venezuela, Colombia, and the Guianas in the north to Brazil, Argentina, and Paraguay in the south, to Bolivia, Peru, and Ecuador in the West. They are excellent swimmers and divers, but also move quickly on land, even over rugged, mountainous terrain. They have a life span of approximately 25 to 30 years. In the wild, their main predators are crocodilians (only the black caiman and Orinoco crocodile, the latter of which is critically endangered, are large enough to take these tapirs, and , the jaguar which often attack tapirs at night when they leave the water and sleep on the riverbank. Young Brazilian tapirs are also attacked by green anacondas. They are known to run to water when scared to take cover.
It is an herbivore. Using its mobile nose, the tapir feeds on leaves, buds, shoots, and small branches it tears from trees, fruit, grasses, and aquatic plants. Picture 1 courtesy of Ernesto Boede and picture 2 courtesy of Rafael Hoogesteijn.

The jabiru is the tallest flying bird found in South America and Central America, the adult jabiru is 120–140 cm (47–55 in) long, 2.3–2.8 m (7.5–9.2 ft) across the wings, and can weigh 4.3–9 kg (9.5–19.8 lb), sexual dimorphism is high, possibly the highest of any stork, with males being about 25% larger than females. Males weigh an average of 6.89 kg (15.2 lb) whereas females weigh an average of 5.22 kg (11.5 lb). Large males may stand as tall as 1.53 m (5.0 ft).

It is most common in the Pantanal region of Brazil in the Llanos region of Venezuela and the Eastern Chaco region of Paraguay. The jabiru lives in large groups near rivers and ponds, and eats prodigious quantities of fish, molluscs, and amphibians. It will occasionally eat reptiles, bird eggs and small mammals.

The giant South American turtle is the largest river turtle in South America, females weight 30 to 45 kg and their carapace measures up to 90 cm long, males are smaller with carapaces measuring 50 cm. It has a broad, domed and streamlined carapace for active swimming in moderate river currents. The colour may be influenced by the algae that is attached to it, but is usually olive green to brown in colour. This turtle belongs in the family Pelomedusidae, which contains the side-necked turtles, and has a long neck which can be withdrawn horizontally within the shell, leaving it partly exposed, rather than retracting it in a vertical 'S' bend as in most other turtles).
Distribution: Caribbean drainages of Guyana and Venezuela, upper Amazon tributaries in Bolivia, Peru, Colombia, Venezuela, and Brazil, Ecuador, Trinidad.
Type locality: South America.

Electric Eel (Electrophorus Electricus)
Electric Eels are found in the waters of South America, the bigger ones are capable of generating more than 600volt of electric shock through 28ft of still water. The shock that the electric eel produces is enough to harm any large mammal, including humans. Electric eels can grow up to 2 metres and weight up to 20 kg and only need to surface for air every 10 minutes due to the eels complex circulatory system. Electric eels tend to live in muddy beds in calm water, eating fish and small mammals.
Despite the name electric eel, the electric eel is actually related most closely to a catfish and not the common eel fish and many electric eel adults tend to be smaller than their eel fish counterparts.

Hoplias malabaricus, also known as the wolf fish, it is a predatory Central and South American freshwater ray finned fish of the characiform family Erythrinidae.

Found in most river systems and in the following countries; Argentina, Bolivia, Brazil, Colombia, Costa Rica, Ecuador, French Guiana, Guyana, Paraguay, Peru, Suriname, Trinidad and Tobago, Uruguay and Venezuela

Can anyone provide a complete timeline and bloodlines of Sabi Sands lions?  Who related or sired who?

Also on cannibalism, which offspring chased off/kill their elders/relatives?  I am reading a lot of different stories and curious.  When a male lion kills another, can't he detect (in a strange animal way) if his victim is blood related?  Thanks.

Size
Goliat African Tiger Fish are the largest species of African tiger fish. The average adult specimen will be two to three feet long and approximately 25 pounds. The current world record is 99 pounds, three ounces and was caught in 1987 by Daniel Neuville. In an aquarium, it is exceptionally rare to see a specimen larger than two feet. These things have attained huge popularity thanks to their inclusion in an episode of River Monsters with Jeremy Wade, you find them in the huge Congo River and  tributaries they are very difficult to catch they are very powerful, their jaws are armed with huge teeth almost as big as the ones of the Great White Shark.

They are very social animals that live in groups of 5 to 15 individuals, they are very important prey of Jaguars, they are very aggresive when cornered, Jaguars always attack the last pecari of the group from behind because they have been known to attack Jaguars in groups and can really do a lot of damage. They can be dangerous to humans too, many hunters need to go high in a tree to avoid them and they wait sometimes for 20 minutes under the tree..
