Jaguars are not man eaters I am sure you wont find a book of Jaguar man eaters they always stay away from the man.

I forgot to add "how about the jaguar's book of past distribution and habitat and other parts of their range like in Central America and far down in Pampas or Patagonia?" I am interested in ecology, distribution, habitat, size, life cycle, and other things of the jaguar. I wish I can write a book about jaguar (Korean language book) since jaguar is not really well known animal in Korea. So I am looking to find many good information of jaguar I did heard of Rafael Hoogesteijn and Edgardo Mondolfi. They actually wrote good research paper in 1996. The Remarkable Journey of the Jaguar, El Jaguar Tigre Americano, and Almeida. Is it possible to find it these days? I hope it won't be expensive. Another good hunting book (or mean-eating jaguar) is Sasha Siemel. I never actually read his book, but some people think him as 100% rubbish. Many of them think this guy just killed jaguars to become famous. One riddle is how did they survived in southern USA? The jaguar strongly associated with the presence of water. Many places of the Arizona, new Mexico, California, and Texas are desert, semi desert, dry forest, steppe, and others dry habitats. If jaguar was also once lived in entire Brazil, then how did jaguar survived in desert like Lençóis Maranhenses National Park? It is almost impossible to find any information of the jaguar lived in the USA. It's the same for other parts of the South America besides Los Llanos, Pantanal, and Amazon. Life of the jaguar in Andean mountains, cloud forest, Pampas (and Patagonia if they lived there) may have been interesting as well.  *This image is copyright of its original author It isn't 100% accurate map, since jaguar once discovered in California and most part of Texas. Thanks for those 3 books, but please let me know if you know good books about jaguar in central America and other places in South America. Also, past distribution of jaguar and its range map.

Thank you for amazing photo! I guess those two jaguars are no bigger than 90kg. What about head to body length. Majority book and internet are mentioning jaguar's body size as 110-185 cm. I haven't found any jaguar with 180 cm body length when I actually looked up size table. What are the jaguar's actual nose to body and total length including tail? This is just one photo I found.  *This image is copyright of its original author

I am sure you won't find a Jaguar measuring over 160 cent long, I have seen the same information you found in internet but the only big cats that grow over 180 cent long in head and body length excluding the tail are Tigers and Lions.
The size of the Jaguar
It's interesting that male Los Llanos jaguar is bigger and heavier than male Pantanal jaguar, but female Los Llanos jaguar is much smaller than female Pantanal jaguar.  *This image is copyright of its original author Jaguar's skull size. Both male & female Pantnal jaguar's skull is bigger than both male & female Llanos jaguar's skull. Interesting studies is that female Los Llanos jaguar is way smaller than female Pantnal jaguar while there is almost no size difference between male Pantanal jaguar and Los Llanos jaguar.  *This image is copyright of its original author  *This image is copyright of its original author

What's your opinion of these? I honestly think there is no size difference between male Pantanal jaguar and male Los Llanos jaguar. They probably caught bigger male jaguars in Los Llanos and smaller male jaguars in Pantanal. Question is female's size. Is it because of prey abudance in Pantanal compare to the Los Llanos? Male jaguar can attack any size of animals in Central and South America, while female jaguar is different. That's why female Pantanal jaguar is larger than female Los Llanos jaguar. There is no doubt jaguar is a king of nature in Pantanal while Los Llanos has equally powerful animal like Orinoco crocodile and Green Anaconda. I personally don't think Orinoco crocodile and Black caiman is predating huge male jaguar unless jaguar is swimming in water since 100 kg male jaguar is extraordinarily powerful animal. I think they are both number 1 predator. But female jaguar is different story since they are smaller. Maybe that's why? That's why skull size difference between Pantanal jaguar and Los Llanos jaguar? I don't really know what are the common prey animal in Los Llanos. There are 140-150 kg jaguar records in Los Llanos from old hunting. Is it true that the Los Llanos jaguar is the second largest jaguar next to the Pantanal jaguar? I think they are both the biggest jaguar in modern time. My guess is that size of the Los Llanos jaguars may have been decreased due to hunting in 60 years ago. Can you find recent size record of the Los Llanos jaguar? What if we put few jaguars in Amazon, Orinoco delta, and Mount Romraima or Angel fall area in Canaima National Park. Do you think they will grow huge like Los Llanos jaguar? Or jaguar in those area are genetically smaller? Why are they smaller? Is it because of dense jungle? Or Smaller prey? swamp and water environment?

The number of Orinoco Crocodiles today is about 2000 in the wild so you can say that they dont compete with Jaguars in Venezuela, Orinoco Crocodiles were over hunted, they are too big and strong for any Jaguar, in the Lanos you can find a big number of Anacondas today but a big Jaguar can hunt a big Anaconda out of the water, normally the bigger Green Anacondas over 5 meters long stay all the time in the water. I really dont know if Jaguars in Amazon, Orinoco Delta, and Mount Roraima would grow as big as the ones in los Llanos if they had greater numbers of prey like the ones they have in Los Llanos but they will grow more for sure. I think they are smaller in those regions because they dont have the same prey availability they find in Los Llanos.

The Atlantic forest jaguar
The Atlantic Forest is one of the highest biodiversity hotspot, but it is considered the most threatened biome on the planet due to deforestation and overpopulation. Despite so little forest remaining, the Atlantic Forest remains extraordinarily lush in biodiversity and endemic species, many of which are threatened with extinction. Approximately 40 percent of its vascular plants and up 60 percent of its vertebrates are endemic species, meaning they are found nowhere else in the world. Sadly, in the past 400 years, nearly 250 species in the region have ceased to exist due to human activities in the region. The jaguar is the king of the Atlantic Forest just like jaguar of the Pantanal and they are very elusive. Sadly, the Atlantic forest jaguar is considered as the most endangered population of jaguar in this world. Conservation organization and media are just always talking about situation in Asia and Africa, but no one talks about these region and central America.  *This image is copyright of its original author Jaguar captured on film by a camera trap in the the Carlos Botelho State Park, Brazil in April 2017.  *This image is copyright of its original author Rare footage of jaguar in the Upper Paraná Atlantic Forest (Alto Paraná Atlantic forests), Argentina on 9/17/2010 from WWF. |
