Lack of Light
The lack of light requires creatures to have special adaptations to find food, avoid predators, and find mates. Most animals have very large eyes with retinas constructed only of cones, which increases sensitivity. Many animals have also developed large feelers to replace peripheral vision. To be able to reproduce, many of these fish have evolved to be hermaphroditic, eliminating the need to find a mate. Many creatures have also developed a very strong sense of smell to detect the chemicals released by mates.

Famous quotes containing the words lack of, lack and/or light:
“Today I begin to understand what love must be, if it exists.... When we are parted, we each feel the lack of the other half of ourselves. We are incomplete like a book in two volumes of which the first has been lost. That is what I imagine love to be: incompleteness in absence.”
—Edmond De Goncourt (1822–1896)
“Poverty is relative, and the lack of food and of the necessities of life is not necessarily a hardship. Spiritual and social ostracism, the invasion of your privacy, are what constitute the pain of poverty.”
—Alice Foote MacDougall (1867–1945)
“Heaven doth with us as we with torches do,
Not light them for themselves; for if our virtues
Did not go forth of us, ‘twere all alike
As if we had them not.”
—William Shakespeare (1564–1616)
