These things can be pretty nasty, the camera (and my hand) was like 4-5cms away!

/ / ScienceDaily (Jan. 10, 2002) AUSTIN, Texas Half of all living bird and mammal species will be gone within 200 or 300 years, according to a botany professor at The University of Texas at Austin. (link) / / Although the extinction of various species is a natural phenomenon, the rate of extinction occurring in today’s world is exceptional as many as 100 to1,000 times greater than normal, Dr. Donald A. Levin said in the January-February issue of American Scientist magazine. (link) / / If present trends continue, a mass extinction is very likely underway. The evidence is pieced together from details drawn from all over the world, but it adds up to a disturbing picture. This time, unlike the past, it’s not a chance asteroid collision, nor a chain of climatic circumstances alone that’s at fault. Instead, it is chiefly the activities of an ever-growing human population, in concert with long-term environmental change. (link) / / The typical rate of extinction differs for different groups of organisms. Mammals, for instance, have an average species “lifespan” from origination to extinction of about 1 million years, although some species persist for as long as 10 million years. There are about 5,000 known mammalian species alive at present. (link) / / Given the average species lifespan for mammals, the background extinction rate for this group would be approximately one species lost every 200 years. Of course, this is an average rate; the actual pattern of mammalian extinctions is likely to be somewhat uneven. Some centuries might see more than one mammalian extinction, and conversely, sometimes several centuries might pass without the loss of any mammal species. Yet the past 400 years have seen 89 mammalian extinctions, almost 45 times the predicted rate, and another 169 mammal species are listed as critically endangered. (link)
