apex predator

The only threat to these species is human activity such as hunting, habitat destruction, and climate change. Apex predators also go by the name alpha predators or top predators. Apex predators often have a significant impact on their habitat (when they are also known as a ‘keystone species ‘). This comes in the form both of controlling prey density and restricting smaller predators, which in turn has knock-on effects on the regulation of disease, and maintaining biodiversity in an area. When apex predators are removed from or introduced to new environments they can cause what is termed ‘trophic cascades’ – wide-ranging effects on lower levels of the ecosystem. For example, when Arctic foxes were introduced to sub-Artcic islands , their predation of seabirds was shown to turn grassland into tundra, whilst the recent reduction in sperm whale numbers has caused an increase in the population of large squid. They are found on only five of Indonesia’s 17,500 islands, living in tropical dry forest and savanna areas on Komodo, Rinca, Gili Motang, Flores, and Padar. Komodo dragons have no predators in their environment, and are apex predators that feed on any type of meat including carrion, water buffalo, deer, pigs, and have even been known to kill and eat humans . Their saliva contains toxic bacteria, ensuring anything escaping their powerful legs and sharp teeth will die of blood poisoning within 24 hours. The Tasmanian devil is a unique dog-like carnivorous marsupial that once wandered all of Australia, but is now restricted to the island state of Tasmania, with a small breeding population in New South Wales. Tasmanian devils survive on small prey like birds, fish, frogs, and insects, and are happy to scavenge. These apex predators have a solo hunting technique that’s a combination of ambush and speedy attack, combined with an exceptionally strong bite per body mass . Giant petrel are large sea birds (with wingspans up to 2 meters) found around Antarctic and sub-Antarctic islands. Giant petrel are known to kill larger birds – like albatross – by drowning or battering, then eat them, and also hunt squid, fish, and krill. As well as hunting they are happy to scavenge, often being found around seal and whale carcasses. Golden eagles are the largest bird of prey in North America, and one of the world’s largest eagles , and dominate their habitats of mountains, hills, cliffs, and coniferous forests as a true apex predator . There is a limited supply of this prey in the golden eagle’s mountainous habitat, so one breeding pair may defend an area of more than 100 square kilometers. These predatory birds have excellent eyesight and are able to spot small prey from great heights, after which they dive at incredible speed and use their talons to snatch the prey from the ground. Their diet is mainly grouse and hares, but also each other small mammals, reptiles, and fish. Jaguars are found in South and Central America, preferring wet lowland habitats, swampy savannas, and tropical rainforests. These big cats are masters of their habitat and are known to almost anything they can catch, including deer, crocodiles, snakes, monkeys, deer, sloths, tapirs, turtles, eggs, frogs, and fish. Despite its name, the king cobra is not really related to the Naja (true cobra) genus. Rather, they are members of their own exclusive genus. Found predominantly in South and South-east Asia, they usually prey on other snakes, including rat snakes and small pythons, and sometimes on other vertebrates such as lizards, birds, and rodents. Brown bears are found across the forests of North America, Europe, and Asia, often living in close proximity to humans. These bears are among the largest land animals alive today, reaching heights of 2.5 meters when standing on their hind legs, and weigh up to 770 kg. This makes the brown bear one of the largest land predators in the world, and a pure apex predator. They are omnivorous, happy to hunt or scave
