An apex predator, also known as a top predator, is a predator at the top of a food chain, without natural predators of its own. Apex predators are usually defined in terms of trophic dynamics, meaning that they occupy the highest trophic levels. They are important in nature conservation because they have powerful effects on other predators, herbivores, and plants.
Humans have hunted many apex predators close to extinction, but in some parts of the world, these predators are now returning. In this article, we will explore 10 types of apex predators from various sources.

10 Types Of Apex Predators
Wolf
Wolves are large canines native to Eurasia and North America, and are known as apex predators, meaning they are at the top of the food chain. There are more than thirty subspecies of wolves, including the dog and dingo.
Wolves are highly specialized for cooperative game hunting, and have physical adaptations to tackle large prey. They travel in nuclear families consisting of a mated pair accompanied by their offspring, and offspring may leave to form their own packs on the onset of sexual maturity and in response to competition for food within the pack.
Wolves primarily prey on elk, deer, moose, and other ungulates, although they also feed on smaller species such as beaver, mice, squirrels, rabbits, muskrats, marmots, grouse, and even songbirds. When hunting large gregarious prey, wolves will try to isolate an individual from its group, and if successful, a wolf pack can bring down game that will feed it for days.
However, one error in judgement can lead to serious injury or death, as most large prey have developed defensive adaptations and behaviours. Predatory attacks may be preceded by a long period of habituation, in which wolves gradually lose their fear of humans, and the majority of victims of predatory wolf attacks are children under the age of 18.
As apex predators, wolves play an extremely important part in a healthy, thriving ecosystem, and help keep the ecosystem in balance by hunting primarily on prey that is weak, sick or elderly, leaving stronger and healthier animals to survive and produce viable young.
Burmese Python
The Burmese python is one of the largest species of snakes, native to a large area of Southeast Asia and listed as Vulnerable on the IUCN Red List. Until 2009, it was considered a subspecies of the Indian python, but is now recognized as a separate species.
Burmese pythons are among the largest snakes on Earth, capable of reaching 23 feet or more in length and weighing up to 200 pounds. They are dark-colored non-venomous snakes with many brown blotches bordered by black down the back.
Burmese pythons are carnivores, surviving primarily on small mammals and birds, but exceptionally large pythons may search for larger food items like pigs or goats.
They have poor eyesight, so instead they stalk prey using chemical receptors in their tongues and heat-sensors along their jaws. They kill by constriction, grasping a victim with their sharp teeth, coiling their bodies around the animal, and squeezing until it suffocates.
Females lay clutches of up to 100 eggs, which they incubate for two to three months. Burmese pythons are a threat to native wildlife and ecosystems of South Florida, where they have large breeding populations and have led to severe declines in Everglades mammal populations.
Alligator snapping turtle
Alligator snapping turtles are apex predators, meaning they are at the top of the food chain and have no natural predators except humans. They are found exclusively in the United States, from northern Florida to eastern Texas and as far north as Iowa, and are almost exclusively aquatic, spending most of their time in the water.
Alligator snapping turtles are primarily carnivorous, feeding on fish and other aquatic animals, but have also been known to eat small mammals and some vegetation. They are most active at night and will scavenge or hunt for food, using their worm-like appendage on their tongues to lure unsuspecting prey.
When hunting, these ambush predators stay motionless in the water and reveal the worm-like appendage on their tongues to lure unsuspecting prey. The largest threat facing alligator snapping turtles has been uncontrolled wild harvesting for their meat, unique shells, and to sell as exotic pets.

The eggs and hatchlings of alligator snapping turtles are preyed on by birds or mammals, but the risk of predation decreases as the turtle gets bigger, so the adult turtle does not have as many predators.
American alligator
American alligators are apex predators, meaning they are at the top of the food chain and have no natural predators except humans. They are found in the southeastern United States, primarily in Florida and Louisiana, and are almost exclusively aquatic, spending most of their time in the water.
American alligators are opportunistic feeders and their diet is determined largely by both their size and age and the size and availability of prey. Most American alligators eat a wide variety of animals, including invertebrates, fish, birds, turtles, snakes, amphibians, and mammals.
Hatchlings mostly feed on invertebrates such as insects, insect larvae, snails, spiders, and worms, as well as small fish and frogs. American alligators have been documented using lures to hunt prey such as birds, which means they are among the first reptiles recorded to use tools.
They create alligator holes, which provide both wet and dry habitats for other organisms, and play an important role as ecosystem engineers in wetland ecosystems. Throughout the year, American alligators bellow to declare territory and locate suitable mates.
The biggest predator of American alligators is humans, but large snakes, such as pythons, and big cats, such as leopards and panthers, sometimes kill and eat these reptiles. The baby and juvenile alligators have to worry about predators, such as large birds, herons, egrets, and carnivores like wild pigs.
American crocodile
American crocodiles are apex predators, meaning they are at the top of the food chain and have no natural predators except humans. They are found in the southeastern United States, primarily in Florida and Louisiana, and in Central and South America, including the Caribbean islands.
American crocodiles are almost exclusively aquatic, spending most of their time in the water. They are opportunistic feeders and their diet is determined largely by both their size and age and the size and availability of prey.
Most American crocodiles eat a wide variety of animals, including invertebrates, fish, birds, turtles, snakes, amphibians, and mammals. Hatchlings mostly feed on invertebrates such as insects, insect larvae, snails, spiders, and worms, as well as small fish and frogs.
American crocodiles have very few predators within their natural environments with the exception of occasional takings by big cats such as lions, jaguars, and tigers.
However, the smaller and much more vulnerable juveniles are preyed upon by a number of animal species around the world from wild pigs, dogs, and large reptiles to birds of prey like eagles.
Despite their aggressive reputation, conflict with humans rarely occurs because of the shy nature of American crocodiles.
Brown bear
Brown bears are apex predators, meaning they are at the top of the food chain and have no natural predators except humans. They are omnivorous, happy to hunt or scavenge for a meal, and one of the largest land predators in the world. A typical brown bear diet consists of fruit, honey, insects, crabs, salmon, birds, eggs, rodents, squirrels, deer, elk, and wild boar.
Brown bears are known to decrease wolf kill rate on two continents, suggesting that competition between apex predators affects predation, the mechanism driving top-down forcing in ecosystems.
A study used gene transcription to analyze 130 brown bear samples from three National Parks and Preserves in Alaska, and found that brown bears are ideal candidates for detecting potentially ecosystem-level systemic perturbations using molecular-based tools.
However, these profiles also likely represent baselines for each unique environment by which future measures can be made to identify early indication of population-level changes due to, for example, increasing Arctic temperatures.
Cape wild dog
Cape wild dogs, also known as African wild dogs, are apex predators, meaning they are at the top of the food chain and have no natural predators except larger social carnivores. They are pack hunters, and their diet consists of a wide variety of prey, including antelopes, warthogs, wildebeest calves, rats, and birds.
African wild dogs have a success rate of around 80% when hunting, which is higher than other predators like lions and leopards. This high success rate is largely due to their teamwork, as a pack of wild dogs will hunt together to capture prey. Lions and hyenas are natural predators to wild dogs, and they also fight with two other predators, leopards and crocodiles.
Humans are the largest threat to wild dog populations, as they are shot and poisoned by farmers who often blame them for killing their livestock.

Habitat loss and habitat fragmentation are also major threats to the species, as human populations expand and wild dogs lose their habitat. Conservation groups are working to protect wild dogs through the creation of protected areas and the protection of major wildlife corridors.
Cougar
Cougars, also known as mountain lions or pumas, are apex predators in ecosystems across North and South America. An apex predator is at the top of the food chain, and nothing hunts and eats them.
Mountain lions are the second largest cat species in the Americas after the jaguar. They are solitary animals and are generally most active at dawn and dusk when they are most likely to be hunting.
Cougars are opportunistic hunters and their diet consists of a wide variety of prey, including deer, elk, moose, mountain goat, bighorn sheep, rodents, lagomorphs, smaller carnivores, birds, and even domestic animals including pets. They are stealthy predators and are skilled at sneaking up on their prey.
Although capable of sprinting, the cougar is typically an ambush predator. They stalk through brush and trees, across ledges, or other covered spots, before delivering a powerful leap onto the back of their prey and a suffocating neck bite.
The cougar is capable of breaking the neck of some of its smaller prey with a strong bite and momentum bearing the animal to the ground. The biggest predator of cougars is humans, but young or injured mountain lions may be preyed upon by larger predators such as bears, wolves, coyotes, eagles, and other mountain lions.
Eagle (various species)
Eagles are apex predators, meaning they are at the top of the food chain and have no natural predators except larger social carnivores. They are birds of prey characterized by powerful talons and beaks, and keen vision that allows them to detect prey during flight.
Eagles generally prey on vertebrates, which can be quite large relative to the size of the bird, and most also eat carrion, with some eating carrion as their main food source. Many eagle species are considered apex predators, including hawks, eagles, buzzards, harriers, kites, vultures, and falcons.
Eagles are skilled hunters and their favorite prey includes other birds, marmots, hares, mice, martens, foxes, and even deer. When eagles attack, they generally swoop down with their feet extended and talons out, and three front talons face forward and the back talon, called the hallux, comes in behind.
Although apex predators are not hunted and killed by other animals, they are not safe from humans, and many of the world’s top predators, including eagles, are threatened by habitat loss, hunting, and other human activities.
Electric eel
Electric eels are apex predators, meaning they are at the top of the food chain and have no natural predators except humans. They are freshwater fish found in South America, and are known for their ability to generate electricity, which they use to stun prey and defend themselves.
Electric eels are carnivorous, going after other animals as their prey, and they hunt in the waters they live in, using the electric current along the length of their underside to attack their target. Apart from being fished by humans, electric eels have no known predators, as they are too dangerous for other species to go after, regardless of water levels.
If the water is shallow, there’s a chance that large land mammals will go after them, but this threat is often deterred with a shock. The electric shock produced by electric eels is strong enough to deter most predators, and they can produce voltage as high as 650 volts.
Although this shock is rarely deadly, it is enough to deter most predators.
