Drop Bears

In the rainforest remnants along the east coast of Australia live one of the most feared marsupials alive today.
Drop bears, Thylarctos plummetus, have been responsible for the loss of livestock, pets and in at least two well documented cases, young children. They are ferocious, determined killers.

At first sight a drop bear looks remarkably like a koala, but they are in fact more closely related to the now extinct Tasmanian Tiger, and the Tasmanian Devil. Carnivorous marsupials are not new. But unlike the Tasmanian Tiger (thyalicine) that died out in the 1930s, and the Tasmanina Devil which is experiencing a population crash because of infectious facial tumours, drop bear numbers have soared since European colonisation, chiefly because of the introduction of feral pigs.

Drop bears are distinguished from koalas by several traits. The first is their size. They are at least two to three times larger than the average koala. A full sized drop bear will reach to a man's thigh. The second most obvious differentiation is that drop bears have two large canine teeth with which they rip their prey. Drop bears also have a reddish-orangy hue to their fur, and much larger hind claws than koalas.

Interestingly, Drop Bears are only very distantly related to koalas. They evolved to look much the same, perhaps because they spend long periods of time - sometimes months - waiting in eucalyptus trees for suitable prey to walk past.

Drop bears usually hunt alone, but if a larger animal is caught, several drop bears will work cooperatively together to kill and eat it.

Their mode of attack is as simple as it is deadly. When a suitable prey is directly under the branch they have been waiting on, they will literally drop on the animal, from a height of up to eight metres, and set about ripping its head off. They will then take the carcase, or bits of it, back up in to the tree, where they will hold on to it for several days until the meat has rotted a bit, before eating it.

Once shot for their fur and teeth (said to be the best ivory in the world) drop bears have been a protected species since 1968.

Since that time, their numbers have climbed dramatically. so much so that in some National Parks a permit is required before you can enter them. To obtain a permit, a bushwalker has to undertake a two-day drop bear safety course.

Protecting oneself against drop bears is relatively easy. Naturally, walking under trees in a drop bear infested area is not a good idea, but because the Australian bush is sometimes so dense, it becomes unavoidable. Drop bears will not drop if they think you are looking at them. A simple pair of glasses with eyes painted on them, placed over a hat so they are looking directly up, is usually sufficient to ward off most drop bear attacks.

Another effective trick is smearing one's skin with Vegemite, a concentrated yeast extract which Australians love to put on their sandwiches. For some reason drop bears - and many Australian insects for that matter - hate the smell, and will go to great lengths to avoid it. Many overseas visitors prefer using this method, because as Vegemite is a deep dark brown that stains readily, it means they get an instant artificial tan.


Drop bear attacks are sudden, vicious and quick. The first sensation is of having been hit on the head with something heavy. It takes a drop bear a few seconds to recover from the fall, and to start biting into your neck. They are not particularly bright creatures, so they will not automatically go for the throat. The best defense in this situation is to locate the drop bear's eyes, and try your best to gouge them out with your thumbs. This will usually force the drop bear to drop to the ground and seek safety in the nearest tree.
Before European settlement, drop bears lived mainly on possums wallabies and kangaroos. Aboriginal tribes would hunt them by putting possum skins over the point of a spear, holding the spear as high as they could above their heads and walking into drop bear infested areas. Seeing the possum, the drop bear would fall on it, thus impaling itself on the spear. It would have taken considerable strength to hunt in this way.A full grown drop bear can weigh in excess of 25 kilos.

Some internet sites maintain drop bears are just an internet joke, along the lines of the stories about baby-eating dingos from the 1980s. Drop bears are no joke. Even the Australian Museum has a page dedicated to warning about the dangers of these creatures.

Fortunately, they have only been two recorded human fatalities from drop bears. Most adults are big enough to ward off an attack before the drop bear finds their throat. Because small children can be the same size as the attacking drop bear, they should be kept near adults at all times when walking in the Australian bush.
