- "No one knows, incidentally, why Australia's spiders are so extravagantly toxic; capturing small insects and injecting them with enough poison to drop a horse would appear to be the most literal case of overkill. Still, it does mean that everyone gives them lots of space."
- ― Bill Bryson, In a Sunburned Country
- "He thought about spiders, twisting thread into beautiful symmetry, taming chaos with ordered nets that greeted the dawn, hung with globes of dew that caught and held cores of sunlight, and tiny images of the world."
- ― Nina Kiriki Hoffman, The Thread That Binds the Bones (1993), Chapter 21.
