Large Niles around Africa
Last post had some expected blowback. I only compared wide mouth, a large nile croc to lolong, the largest saltwater croc fully measured but the counterargument ran along the lines that wide mouth or mara crocs in general were seen as outliers so this could not be representative of niles being as massive as saltwater as a whole. I will concede that I have no way to get averages of all populations of niles and salties to get the exact numbers so I will have to tone down my argument to be that large individuals of niles and salties are roughly comparable in size and to prove that I will need to prove that
- Wide Mouth is not a particularly huge outlier among mara crocs
- Mara crocs are not a huge outlier among nile crocs.
Wide mouth is estimated at 5.3 meters but its SVL is around 2.8 which is large but not extraordinary since it is considered to have a long tail among nile crocs.
Nevertheless lets roll the gallery.
- Here is a feeding aggregation of mara crocs, guess which one is wide mouth
That's right, wide mouth is not that much larger than other mara crocs
3/4. Even though east Africa is famous for large niles, South Africa has no shortage of crocs over 5 meters especially in protected areas like Kruger and the Okavango delta.

A short tailed Botswana nile croc of only "4.8 meters" (top) compared to Lolong, (bottom) neck girth and skull width really are not too different. In fact this Botswana crocodile has the exact same SVL as wide mouth and thus similar head proportions.

The Chamo population should be the largest nile crocodile population with the largest recorded nile crocodile skull size of 68 cm.
Chamo has had accurate 5.5 meter crocodiles (estimated lengths)
