Here, an abundance of turtles keeps competition for food low, and these intensely solitary cats live in much closer proximity.

This gives Luis's cameras an unprecedented view into their social lives.

Luis has recorded jaguars mating, (jaguars growling) wrestling, and even carting off an ill-fated dolphin.

(jaguar growling) The project identifies the individual cats by their rosettes, the spots on their fur.

Each jaguar's pattern is as unique as a human fingerprint.

(tongue lapping) In the last 10 years, Luis's team has documented and named around 40 individual jaguars.

And they're capturing not just behaviors, but personalities.

Alonzo, the 12-year-old dominant male, asserts his right to any female or food on the beach.

Amanda, highly territorial, she seems to be the dominant female.

(waves pounding) And Jorge, a young tough on the cusp of adulthood.

He's been gravitating towards the females in heat.

(paws pounding) (waves pounding) Tonight, Jorge is on the prowl, heading to the beach in search of an easy meal.

And he's well equipped to spot one.

His eyes are backed with a mirror-like tissue that reflects light into his retinas and gives all cats their famous night vision.

Tonight, he finds no turtles, but something for other appetites.

It's Amanda, enjoying her own turtle catch.

Jorge is eager to put his adolescent prowess to the test.

In this rare peek into Jaguar courtship, Jorge and Amanda take playful breaks between couplings.

(jaguars growling) But the interlude is cut short when Alonzo arrives.

(jaguar growling) (jaguar roaring) Jorge beats a hasty retreat.
