Jaguars are apex predators with diverse diets that include more than 85 different prey species. This gives them a specific but prominent role in each ecosystem where they are found.

But evidence shows that local populations across the continent are decreasing at alarming rates. Jaguars’ total range has shrunk by more than half in the past 70 years, mainly because of hunting and habitat loss.
