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 thou fill thy brain with Boston and New York, with fashion and covetousness, and wilt stimulate thy jaded senses with wine and French coffee, thou shalt find no radiance of wisdom in the lonely waste of the pinewoods.”
—Ralph Waldo Emerson (1803–1882)
“Let me obtain forgiveness of thee, Samson,
Afford me place to shew what recompence
Towards thee I intend for what I have misdone,
Misguided; only what remains past cure
Bear not too sensibly, nor still insist
To afflict thy self in vain: though sight be lost,
Life yet hath many solaces, enjoy’d
Where other senses want not their delights
At home in leisure and domestic ease,”
—John Milton (1608–1674)
“For certainly he sank into his grave
His senses and his heart unsatisfied,
And made—being poor, ailing and ignorant,
Shut out from all the luxury of the world,
The coarse-bred son of a livery-stable keeper—
Luxuriant song.”
—William Butler Yeats (1865–1939)
