PASSAGE 1 Night vision may seem like a supernatural power, but many mammals can see at night.
Raccoons, opossums, and red foxes are just a handful of nocturnal mammals whose eyes possess
a greater spectral range than human eyes. In addition to having fewer cones and rods, humans
and most monkeys lack the tapetum lucidum, an cye tissue layer necessary to see radiation in
the dark. The human eye is arguably one of the more deficient optic anatomies in mammalian
species. Some scientists even go so far as to compare human eyes to those of some deep sea fish
and snakes that have limited vision.
1. The phrase fewer cones and rods“ most likely applies to
A. human and monkey's tapetum lucidum
B. raccoon and opossum's spectral range
