Koalas are cute fluffy animals that spend most of their lives on trees looking for fresh eucalyptus trees. The reason for this particular preference is that the animals diet is made up, almost entirely, of eucalyptus leaves. . Now, using the genome as a reference, biologists will be able to keep track of what’s happening in the different koala colonies—and can know better how and when to take action. Koalas, though, evolved the ability to flush the toxins out quickly, so they can eat their way through pounds of leaves each day without getting sick. The eucalyptus plant is the major source of eucalyptus oil, which is used in many products for its antiseptic properties, scent, and flavoring.

Out o… Depends on habitats and regions koalas sometime prefer to eat Blue Gum, Manna Gum, Grey Gum, and Tallowwood. Rebecca Johnson, a conservation geneticist at the Australian Museum in Sydney and the lead author of the study published today in Nature Genetics, was constantly getting calls from state officials and development companies asking for her advice about how help preserve healthy, genetically diverse koala populations around the country. The harmful chemicals are most concentrated in the new leaves and the flowers. Most animals that eat a lot of it could get quite sick -- cats, dogs and horses included -- but koala bears and certain possums can eat it without much worry.

Possums are known to eat large proportions of eucalyptus leaves, ferns, grasses, fruits, mosses, and herbs. Baby koalas are too cute (this is indeed, a fact). Several beetle species feed only on eucalyptus plants, including the eucalyptus snout beetle (Gonipterus scutellatus) and the eucalyptus tortoise beetle (Chrysomelidae spp.). They suspected that the koalas were able to somehow sense how toxic or nutritious each leaf was based its smell. By Eric Novinson. Answer (1 of 2): Yes, another eucalyptus eater is the greater glider, which lives in the rain forests and humid woodlands of eastern Australia, and spends most of its time alone or in pairs. In an earlier 2001 study from Thailand (where the mosquitoes can be downright dreadful), mosquitoes in cage conditions were repelled by turmeric, citronella grass, and hairy basil oils. So she rounded up a team of specialists from around the world who slowly assembled the pieces of the genetic puzzle. Koalas also suffer from a retrovirus, similar to HIV, that weakens their immune systems and makes them even more susceptible to diseases like chlamydia or cancer. The future of the koala, perhaps Australia's best-loved animal, is under threat because greenhouse gas emissions are making eucalyptus leaves - their sole food source - inedible. Wombats and kangaroos will eat young leaves and shoots from eucalyptus saplings.

Unlike koalas, brushtail possums are probably the only arboreal marsupials to feed on different types of plants during their foraging journey.

Brushed Tailed Possum also eats eucalyptus leaves. Koalas live in tall open eucalypt (gum tree) forests. The koala is a pouched mammal or marsupial found in Eastern Australia. An adult koala eats between 200 to 500 grams of leaves each day. The number of koalas in most parts of Australia has declined precipitously over the past few decades, as the eucalyptus forests they inhabit have been shaved down to make way for development and devastating diseases spread.
