Then I took the 195kg at 300cm and then I took the 750kg at 560cm and then I tested this relation with these weights but it obviously did not match but I would still say that a 350cm mugger should likely be 300kg+.

Remember that, sadly, you only have one real weight (the captive one), the other two are estimations and I don't know where you got that 750 kg figure, there is no record about that. In fact, in the webpage of the Wildlife Institute of India they quote a maximum weight of 450 kg, check it:

"The Mugger crocodile is a medium to large crocodilian species; an adult male may reach up to 4.5 meters (18 ft) in length and weigh 450 kg (1000 lbs). It has a distinctive aspect, and is the most alligator like of all crocodile species. While juvenile’s generally have a light tan colouring with some black cross-banding on the body and tail, adult specimens are generally gray to brown."

Also, Whitaker & Whitaker (1984) quote that the maximum size reported is of 5.63 m but they do not provide body mases, check it:

As real (and reliable) weights of big crocodiles are very scarce, I leave you this detail that may be helpfull. In Costa Rica the Dr Brady Barr measured and weighed what could be the biggest American crocodile ever measured and the only actually weighed, all recorded in video. The animal measured 482 cm (incomplete tail) and they estimated probably up to 5 meters and the beast weighed 1,250 lb (567 kg) and final weight excluding gear says it was 540 kg.

Ahh! Then we only have two weights. One is an 111kg @ 274cm estimate by Brander and one real weight of 195kg @ 300cm. And @Ashutosh told me about the 750kg weight but now it indeed seems unreliable.

As for the American crocodile, I’m not sure if I should use the American crocodile to estimate the size of Muggers because I tried using Saltwater crocodile and it did not work so using American Crocodile may also not work.

Unfortunately it’s impossible to get an estimation for the 350cm mugger with just two available weights and measurements to use as surrogates. If I had 5 or even 4 weights and measurements available to use then maybe I could have derived a nearly accurate relation between the weight and length of muggers.

With 4 varying pairs of weights and measurements, I could have made multiple different combinations and averaged them out to get an estimation but with only 2, I can only get a single one (which would obviously be completely unreliable)

As for the saltwater crocodiles, I got an average exponent of around 3.115 [LOG base(higher length/lower length) higher weight/lower weight] but the exponents wildly varied between slightly below 3 to slightly more than 4 so I am guessing that these crocodiles get bulkier as they get longer

But since we have only 2 weights and measurements, it’s impossible to calculate an estimated weight for the mugger killed by Machli. I would still say around 300kg based on just the single mugger specimen.

Nevertheless, thanks a lot friend. You were very helpful just as always. Reply
