Senses
The species on Darwin have all evolved sonar, echo-location using a variety of sounds as their primary sense, rather than perceiving light, as most animals on Earth do. Many have complicated cephalons to aid in this sense. The majority have also evolved biolights; but rather than communicating information in the visible light spectrum, biolights on Darwin IV function in the infrared range, as all Darwinian animals are quite sensitive to that spectrum. It is important to note that their sensory organs to detect light in the infrared spectrum are more comparable to thermoreceptors found in pit vipers or rattlesnakes. The Rimerunner still has one bizarre, retractable, atrophying eye, a remnant from a time when sight-based organisms still had a place on Darwin IV. Also, most species are hermaphrodites.

Famous quotes containing the word senses:
“Considered physiologically, everything ugly weakens and saddens man. It reminds him of decay, danger, impotence; it actually reduces his strength. The effect of ugliness can be measured with a dynamometer. Whenever anyone feels depressed, he senses the proximity of something “ugly.” His feeling of power, his will to power, his courage, his pride—they decline with ugliness, they rise with beauty.”
—Friedrich Nietzsche (1844–1900)
“When the shrivelled skin of the ordinary is stuffed out with meaning, it satisfies the senses amazingly.”
—Virginia Woolf (1882–1941)
“The damned are in the abyss of Hell, as within a woeful city, where they suffer unspeakable torments, in all their senses and members, because as they have employed all their senses and their members in sinning, so shall they suffer in each of them the punishment due to sin.”
—St. Francis De Sales (1567–1622)
