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:
“Both Eliot and Pound condense; their best verse is weighted—Pound’s, with sensual experience primarily, and Eliot’s with beliefs. Where the mind’s life is concerned the senses produce images, and beliefs produce dramatic cries. The condensation is important.”
—R.P. Blackmur (1904–1965)
“Science asks no questions about the ontological pedigree or a priori character of a theory, but is content to judge it by its performance; and it is thus that a knowledge of nature, having all the certainty which the senses are competent to inspire, has been attained—a knowledge which maintains a strict neutrality toward all philosophical systems and concerns itself not with the genesis or a priori grounds of ideas.”
—Chauncey Wright (1830–1875)
“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)
