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:
“Each day I live in a glass room
Unless I break it with the thrusting
Of my senses and pass through
The splintered walls to the great landscape.”
—Mervyn Peake (1911–1968)
“I have almost forgot the taste of fears.
The time has been, my senses would have cooled
To hear a night-shriek, and my fell of hair
Would at a dismal treatise rouse and stir
As life were in’t. I have supped full with horrors;
Direness, familiar to my slaughterous thoughts,
Cannot once start me.”
—William Shakespeare (1564–1616)
“The damned are in the abyss of Hell, as within a woeful city, where they suffer unspeakable torments, in all their senses and members, because as they have employed all their senses and their members in sinning, so shall they suffer in each of them the punishment due to sin.”
—St. Francis De Sales (1567–1622)
