Why Are There No Big Animals In Australia
However on the most fundamental level such incredible growth is impossible because there are no large animals exhibiting these ancient avian traits.
Why are there no big animals in australia. The fact that monkeys did not make the journey to Australia can probably be attributed to geological movement that began 175 million years ago. Learning about Australias extinct fauna helps us to create links through time that relate the animals of the past with those of today and to develop conservation strategies. Snakes kill an average of 2 to 4 people a year here but the number of casualties seem small when you compare it to the 11000 individuals that snakes annually kill in Asia.
A grand total of 21 out of the worlds 25 most venomous snakes inhabit Australia. It is because Australia is an island. It is a secluded landmass with no immigration of animals from other parts of the world.
The earliest cat fossils date back only 10 - 15 million years so. This species doesnt have particularly potent venom but the allergic reaction suffered by 1-2 per cent of the population coupled with the high incidence of bee stings make them second to snakes as the most deadly venomous animal in Australia. There are a number of factors that prevent this titanic rise including a lack of ecosystems and the systematic elimination of large mammals as a result of human activity and development.
Australia probably has between 200000 and 300000 species about 100000 of which have been described. Australias coast also stretched further into the Timor Sea. But there is still so much we dont know about Australias native animals.
They can be found all over Australia except for Tasmania although they mainly live in the countrys outback. There are not more dangerous animals in Australia then elsewhere. So an exceptionally large proportion of australias plants and animals are endemic meaning they naturally exist nowhere else in the world.
Here we explore weird and wonderful facts about 10 of them. Australia possesses a unique assemblage. The distribution of climates topography and soils that has produced the zones and ecological variation of Australian vegetation has also been reflected in the distribution of animal life.
