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:
“If I could put my hand on the north star, would it be as beautiful? The sea is lovely, but when we bathe in it the beauty forsakes all the near water. For the imagination and senses cannot be gratified at the same time.”
—Ralph Waldo Emerson (1803–1882)
“Things perceived by the senses are immediately perceived by the senses; and things immediately perceived by the senses are ideas; and ideas cannot exist without the mind, their existence therefore consists in being perceived; when therefore they are actually perceived, there can be no doubt of their existence.”
—George Berkeley (1685–1753)
“When the shrivelled skin of the ordinary is stuffed out with meaning, it satisfies the senses amazingly.”
—Virginia Woolf (1882–1941)
