Kangaroos face few natural predators, aside from humans and wild dogs called dingoes. Heat, drought, and hunger due to vanishing habitat are among the largest threats to kangaroos.
The dingo and wedge-tailed eagle are the natural enemies of the kangaroo. But humans are also an enemy of the kangaroo.
Detailed autopsies were performed on 17 of the dead kangaroos: primary predation was the only significant gross patho- logical finding; the dingoes had eaten portions from about half the kangaroos killed. The daily rate of killing was estimated to be about 0.38 kg prey per kg predator.
There are few non-human predators on Red Kangaroos. Dingoes are probably the most significant, while foxes and wedge-tailed eagles can take young animals.
They are an extraordinary and now rare group of animals but Earth has had some formidable marsupial carnivores. These pouched killers have included lions, wolves, and even sabretooths. Today, the only large marsupial carnivore left in existence is the Tasmanian Devil, and that is on the brink of extinction.
Rottnest Island is known worldwide to be the home of the happiest animal on Earth – the Quokka (Setonix brachyurus). Close relatives of Wallabies, these tiny animals are found all over Rottnest Island, where their survival is largely attributed to the exclusion of any natural predators.
The hyena's reputation as having the world's most vicious bite is a myth, says an international team of researchers. For its bodyweight, the title goes to Australia's Tasmanian devil, a marsupial that has a bite as strong as a dog three times its weight.
Kangaroos have few natural predators: Dingoes , humans, Wedge-tailed Eagles and, before their extermination, Tasmanian Tigers . Introduced carnivores, such as wild dogs and foxes prey on the young, and introduced herbivores compete with kangaroos for food.
These impressive carnivores are capable of reaching up to seven metres in length and weighing over 1,000 kilograms. At this size, they are capable of eating wild pigs, deer, kangaroos and even cattle or wild buffalo!
Dingoes, wedge tailed eagles and red foxes are the major predators of kangaroos in arid Australia, although eagles and foxes generally take juvenile kangaroos.
All kangaroos are large animals with powerful arms and massive feet. The largest is the iconic red kangaroo, which can easily tower over a tall human. Kangaroos use their arms, claws and feet as weapons in male-male combat, and for self-defense against predators such as dingoes and wedge-tailed eagles.
The puppies were regarded as a delicacy, although these were sometimes reared by the Aborigines for hunting. According to Hassell (1936, p. 688) the young people were not allowed to eat dingos, and if they caught one then they had to give it to the old people. Dingoes were not cut up before being cooked.
Many Australian supermarkets now stock various cuts of kangaroo including fillets, steaks, minced meat and 'Kanga Bangas' (Kangaroo sausages). Many Australian restaurants serve Kangaroo meat. Kangaroo meat has been exported since 1959.
#3 You need to rely mainly on 'unpalatable' plants.
Plants with oily or fragrant foliage. Plants with high oil content (including some which have fragrant foliage) include species of Eremophila, Prostanthera, Westringia, Eriostemon, and Myoporum appear almost totally unpalatable to 'roos.
“Kangaroos and dogs just do not mix. Kangaroos see dogs as a threat and get spooked by them,” Evans said. “The main message people should remember is that kangaroos may look cuddly and furry but they are wild animals and people should keep their distance and keep dogs on leads around them.”
Beach bum kangaroos are sometimes seen and can be very friendly and approachable.
Males fight for access to females by biting, kicking, and boxing. These methods are also used by kangaroos to defend themselves against predators. With their agile arms, they can spar vigorously.
"There's a very strong instinct — kangaroos will go to water if they're threatened by a predator," kangaroo ecologist Graeme Coulson from the University of Melbourne says. "In the case of a big male, they can definitely drown dogs.
So, if a lion and kangaroo fight, the lion will win. The lion is a stealthy hunter who can sneak up on the kangaroo and pounce before the marsupial knows what's happening. Additionally, lions are intelligent hunters and will adapt their strategy depending on the circumstances.
Kangaroos and wallabies that are used to being fed can approach people expecting food. When there is no food, they may become aggressive. Today, people rarely live in close contact with large wildlife. As a result, we have lost much of our wariness and first-hand knowledge of these animals and how they live.
Said to be one of the most dangerous animals in Australia, the Saltwater Crocodile is an aggressive and territorial animal, and is the largest reptile in the world in terms of their mass – known to reach over 1000kg!
The Nile crocodile is the most aggressive animal in the world mostly because it considers humans a “regular part of its diet” according to a-z-animals.com. The animal can weigh up to 1,650 pounds and can be found in 26 countries in sub-Saharan Africa.
In terms of size and strength, large predators such as bears and lions are typically the most difficult to fight. These animals can be unpredictable and very dangerous, and they usually have an extremely powerful bite and razor-sharp claws.
