Panthers, with their striking black fur and piercing yellow eyes, are fierce and elegant hunters. While the term "panther" often conjures images of a sleek, black cat, it's important to understand that panthers aren't a specific species. Rather, the term refers to any leopard or jaguar with melanism, a high amount of black pigment in their fur. The two main types of panthers are the melanistic jaguar (Panthera onca) and the melanistic leopard (Panthera pardus). Regardless of their specific type, panthers are apex predators with a diet that reflects their adaptability and the diverse environments they inhabit.
General Dietary Habits
Panthers are generally nocturnal carnivores, meaning they are most active at night and primarily eat meat. However, they may occasionally consume fruit. They typically prey on small-to-medium-sized herbivores found in their humid forest and jungle habitats. As apex predators, panthers aren't very picky eaters and will feed on just about any animal that moves.
Prey Preferences of Different Panther Types
While both melanistic jaguars (Panthera onca) and melanistic leopards (Panthera pardus) are opportunistic hunters, there are some differences in their preferred prey. The highest percentage of Panthera pardus’ diet consists of wild hogs, boars, and deer. Panthera onca frequently preys on peccaries, deer, and tapirs. However, both types of panthers will also consume smaller mammals such as capybaras, agoutis, pacas, raccoons, opossums, armadillos, and rabbits.
Hunting Techniques
Panthers rely on stealth and speed to capture their prey. They are expert hunters who stalk their prey slowly and quietly, waiting for the right moment to strike. They have extremely strong jaws and sharp teeth that can crush the skulls of even large mammals and reptiles with ease. Unlike many predatory animals that chase their prey for long distances, panthers prefer to ambush their prey after stalking them for hours or even days. Instead of chasing their prey until it becomes too tired to keep running, a panther will follow its prey silently, staying out of sight and only revealing itself mere seconds before striking. Panthera onca frequently hunts near water for aquatic prey, while Panthera pardus prefers to stay on land and is believed to be even stealthier. Panthera pardus may even drag its kills up trees to avoid other predators.
Competition and Predators
Because panthers are apex predators, they don’t really have any natural predators to watch out for, other than humans. However, they do have quite a bit of competition for food from other large carnivores, primarily other big cats. In some cases, these big cats may even prey upon and eat each other.

The Florida Panther: A Case Study
The Florida panther (Puma concolor couguar) is a North American cougar found in South Florida’s hardwood hammocks, pinelands, and swamps. Once found across the Gulf Coast states, the Florida panther now survives only in southwestern Florida. The Florida panther symbolizes what is left of natural Florida and is a guiding force behind much of the Florida Wildlife Federation’s work. This iconic species was one of the first animals listed under the Endangered Species Act.
Diet of the Florida Panther
Florida panthers are carnivorous and primarily hunt white-tailed deer, wild hogs, raccoons, armadillos, and smaller mammals. As opportunistic predators, they adapt their diet based on prey availability, occasionally consuming birds, reptiles, and scavenging carcasses when necessary. Their hunting strategy relies on stealth and ambush, using their powerful hind legs to leap and take down prey with a swift, decisive attack.
Dietary Needs and Habitat
Because panthers require large home ranges to find enough food, habitat loss can make hunting more difficult, leading to increased competition for resources. While deer and wild hogs make up the bulk of their diet, smaller prey like raccoons and rabbits become more important when larger game is scarce. To maintain their health and fitness, adult panthers need to consume the equivalent of about 1 deer or hog per week. Panthers in Everglades National Park are smaller and fewer because much of the park consists of wetlands, while panthers need uplands in order to thrive. A panther has to kill and eat about 10 raccoons to equal the food value of 1 deer.
Threats to the Florida Panther
The biggest threats to the Florida panther are habitat loss and fragmentation, which have drastically reduced the species’ range and forced individuals into smaller, isolated areas. As human development continues to expand, vital panther habitat is being lost or divided by roads, neighborhoods, and agricultural land. One of the leading causes of panther deaths is vehicle collisions. As panthers are forced to navigate roadways in search of territory, prey, or mates, many are struck and killed by cars. Additionally, habitat fragmentation leads to genetic isolation, which can cause severe health problems within the population, such as heart defects and skeletal abnormalities.
Conservation Efforts and Diet
GPS tracking has determined that habitat selection for panthers varies by time of day for all observed individuals, regardless of size or gender. They move from wetlands during the daytime, to prairie grasslands at night. The implications of these findings suggest that conservation efforts be focused on the full range of habitats used by Florida panther populations. Protecting panther habitat ensures the preservation of Florida’s forests, wetlands, and grasslands, safeguarding the rich biodiversity that depends on these ecosystems.

Mercury Contamination and Diet
Scientists first became aware of the potential threat of mercury to panthers in south Florida in 1989 when a female panther from the park died. An immediate cause of death could not be determined, but later tests revealed that her liver contained high levels of mercury. That same year, the State of Florida found high levels of mercury in fish from the Everglades. As mercury moves through the food chain, it accumulates in ever-greater quantities in the tissue of each predator. Studies found that mercury concentrations in panther tissues were lowest north of Interstate Highway 75 where adequate deer and hogs were available and highest in the Everglades and the southern part of Big Cypress National Preserve where consumption of raccoons was highest. Raccoons are thought to have been the major source of mercury in Florida panthers at that time.
Hunting Behavior and Diet Composition
Panthers, like most cats, are solitary hunters and are most active at dawn and dusk. When hunting, panthers stalk their prey, moving silently and then freezing their motion to avoid detection. Unlike dogs and wolves, that chase their prey until it tires, panthers rush short distances and spring as far as 15 feet for the kill. With claws extended, their front paws grasp the prey around its neck and shoulders while the claws of the hind feet dig into the prey's flanks. Panthers usually kill large prey by a bite to the back of the neck severing the spinal cord or by a suffocating bite to the throat. After the kill, a panther will drag large animals such as deer or hog into an area of thick vegetation. The ribs are usually chewed off and the body cavity opened. The heart, liver, and lungs are eaten, as well as the large muscle masses of the shoulders and hindquarters. The internal organs provide vitamin A and other nutrients. The large bones are broken and chewed. The panther often removes the stomach and intestines and covers them nearby with leaf litter and twigs. Smaller animals such as raccoons and rabbits are usually eaten in their entirety. Panthers may consume 20 to 30 pounds of meat at one time. After the panther has its fill, it rakes leaves, twigs and other debris over the carcass in what biologists refer to as a cache. This helps hide and protect the carcass from scavengers. If it is not too warm and humid, the panther may return to feed on the carcass for several days.
Studies have revealed that most of a panther’s diet is natural prey such as deer, wild hogs, and raccoons. Biologists examined scats, found while tracking panthers, as well as stomach contents and feces collected during the necropsy of dead panthers. They documented that nearly 70 percent of a panther’s diet comes from deer, wild hogs, and raccoons. Domesticated animals such as goats, sheep, and calves are taken by panthers in areas where this prey is available. However, domesticated prey constitutes only a small part of the panthers’ diet, according to these studies.
