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:
““Reason” causes us to falsify the testimony of the senses. To the extent that the senses show becoming, passing away, and change, they do not lie.”
—Friedrich Nietzsche (1844–1900)
“Perhaps, on the whole, embarrassment and perplexity are a kind of natural accompaniment to life and movement; and it is better to be driven out of your senses with thinking which of two things you ought to do than to do nothing whatever, and be utterly uninteresting to all the world.”
—Margaret Oliphant (1828–1897)
“You know, Frank, I’m beginning to get a new perspective on this crawling little animal known as man. Why a dog or a cat or a bird is cleverer than any human. They sense me immediately. But these shrewd detectives of yours—. Take away one of man’s senses and you render him helpless.”
—Lester Cole (1904–1985)
