I see a LOT of people on DA mixing up their big cats. But, naturally, the two most common cats to be confused by are the leopard and the jaguar.
So I made this.
Jaguars have a central spot inside their rosettes. They're also stalkier in build, have a broader skull, and a wider jaw. Their fur is short and coarse, and despite being similar in size, they usually weigh far more than their smaller African cousins.
Feel free to use this image for educational purposes and reference. I'm honestly surprised that more people don't care to know the difference between these two cats.
