It has more things that will kill you than anywhere else




Australia has secrets. Every year, scientists are discovering new species that have been around for centuries, hidden by Australia’s vast, harsh land. Today scientists announced just such a find from the sea.

This newly discovered carnivorous sea squirt traps fish and other prey in its funnel-like front section, scientists announced today. Most of the 2,000 or so known sea squirt species are filter feeders that strain plankton from seawater. Pretty cool huh?

Consider these words from Bill Bryson, from his book entitled “In A Sunburned Country”

It is the home of the largest living thing on earth, the Great Barrier Reef, and of the largest monolith, Ayers Rock (or Uluru to use its now-official, more respectful Aboriginal name). It has more things that will kill you than anywhere else.

Of the world’s ten most poisonous snakes, all are Australian. Five of its creatures—the funnel web spider, box jellyfish, blue-ringed octopus, paralysis tick, and stonefish—are the most lethal of their type in the world. This is a country where even the fluffiest of caterpillars can lay you out with a toxic nip, where seashells will not just sting you but actually sometimes go for you. Pick up an innocuous cone shell from a Queensland beach, as innocent tourists are all too wont to do, and you will discover that the little fellow inside is not just astoundingly swift and testy but exceedingly venomous. If you are not stung or pronged to death in some unexpected manner, you may be fatally chomped by sharks or crocodiles, or carried helplessly out to sea by irresistible currents, or left to stagger to an unhappy death in the baking outback. It’s a tough place.

In short, there was no place in the world like it. There still isn’t. Eighty percent of all that lives in Australia, plant and animal, exists nowhere else. More than this, it exists in an abundance that seems incompatible with the harshness of the environment. Australia is the driest, flattest, hottest, most desiccated, infertile, and climatically aggressive of all the inhabited continents. (Only Antarctica is more hostile to life.) This is a place so inert that even the soil is, technically speaking, a fossil. And yet it teems with life in numbers uncounted. For insects alone, scientists haven’t the faintest idea whether the total number of species is 100,000 or more than twice that. As many as a third of those species remain entirely unknown to science. For spiders, the proportion rises to 80 percent.

You take my point again, I’m sure. This is a country that is at once staggeringly empty and yet packed with stuff. Interesting stuff, ancient stuff, stuff not readily explained. Stuff yet to be found.

Trust me, this is an interesting place.
