Strangely, it tends to be the second class of animals (the Odd) that are more dangerous. The creature that kills the most people each year is the common Wombat. It is nearly as ridiculous as its name, and spends its life digging holes in the ground, in which it hides. During the night it comes out to eat worms and grubs. The wombat kills people in two ways: First, the animal is indestructible. Digging holes in the hard Australian clay builds muscles that outclass Olympic weightlifters. At night, they often wander the roads. Semi-trailers (Road Trains) have hit them at high speed, with all 9 wheels on one side, and this merely makes them very annoyed. They express this by snorting, glaring, and walking away. Alas, to smaller cars, the wombat becomes an asymmetrical launching pad, with results that can be imagined, but not adequately described.
this is either from, or simply highly reminiscent of, “last chance to see”, which happens to be my absolute favorite douglas adams book.
