In particular, there seems to exist disagreement as to whether the Nile [3] or the Amazon [4] is the world's longest river. The Nile has traditionally been considered longer, but in 2007 and 2008 some scientists claimed that the Amazon is longer [5] [6] [7] by measuring the river plus the adjacent Pará estuary and the longest connecting tidal ...
After Nile crocodiles reach 2 m (6 ft 7 in), the significance of most invertebrates in the diet decreases precipitously. [4] [7] An exception to this is in Uganda and Zambia, where subadults and adults of even large sizes, up to 3.84 m (12 ft 7 in), may eat very large numbers of snails. Nearly 70% of the crocodiles examined by Cott (1961) had ...
For context, the volume of an Olympic-size swimming pool is 2,500 m 3 (88,000 cu ft). The average flow rate at the mouth of the Amazon is sufficient to fill more than 83 such pools each second. The estimated global total for all rivers is 1.2 × 10 6 m 3 /s (43 million cu ft/s), [1] of which the Amazon would be approximately 18%.
The Nile is the longest river in Africa. It has historically been considered the longest river in the world, [3] [4] though this has been contested by research suggesting that the Amazon River is slightly longer. [5] [6] Of the world's major rivers, the Nile is one of the smallest, as measured by annual flow in cubic metres of water. [7]
In 2009, a peer-reviewed article, was published, concluding that the Nile is longer than the Amazon by stating a length of 7,088 km (4,404 mi) for the Nile and 6,575 km (4,086 mi) for the Amazon, measured by using a combination of satellite image analysis and field investigations to the source regions.

The Nile crocodile (Crocodylus niloticus) is a large crocodilian native to freshwater habitats in Africa, where it is present in 26 countries. It is widely distributed in sub-Saharan Africa, occurring mostly in the eastern, southern, and central regions of the continent, and lives in different types of aquatic environments such as lakes, rivers, swamps and marshlands.

The Amazon basin is the part of South America drained by the Amazon River and its tributaries. The Amazon drainage basin covers an area of about 7,000,000 km 2 (2,700,000 sq mi), [ 1 ] or about 35.5 percent of the South American continent.
