In the total darkness of a deep natural cave, what type of adaptations do you expect to see in animals?

A)adaptations relating to bright and colorful markings on the skin

B)adaptations relating to an increase in non-sighted sensory input

C)adaptations relating to using sunlight as a food source

D)adaptations relating to the conservation of limb length

The answer is B

Explanation: In humans as well as other animals will notice an increase in sensory input when they are deaf or blind. So when animals live in total darknes, eventually they will no longer even have eyes and gain better hearing for their surroundings. There is a type of fish like this in a recently discovered cave that before then was completely sealed off and was in total darkness.
