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:
“The senses interfere everywhere, and mix their own structure with all they report of.”
—Ralph Waldo Emerson (1803–1882)
“The future of America may or may not bring forth a black President, a woman President, a Jewish President, but it most certainly always will have a suburban President. A President whose senses have been defined by the suburbs, where lakes and public baths mutate into back yards and freeways, where walking means driving, where talking means telephoning, where watching means TV, and where living means real, imitation life.”
—Arthur Kroker (b. 1945)
“Whether or not his newspaper and a set of senses reduced to five are the main sources of the so-called “real life” of the so- called average man, one thing is fortunately certain: namely, that the average man himself is but a piece of fiction, a tissue of statistics.”
—Vladimir Nabokov (1899–1977)
