Wow. What a beast!
The big cat leaped into the water to catch the caiman and wrestled it to the river bank.
Essentially, caimans are small alligators but more agile and crocodile-like in their movements, and have longer, sharper teeth. They are known to grow to about 7ft.
Jaguars are strong swimmers and rivers provide prey in the form of fish, turtles, or in this case, a caiman.
