What anatomical structure maximizes the tiger's ability to see in low light?

Answer

The tapetum lucidum, which reflects light back through the retina a second time.

The tapetum lucidum is a mirror-like layer behind the retina that reflects light that has already passed through the sensory cells, maximizing the utilization of scarce photons for a brighter image.
