Best Answer

A reflective membrane called the tapetum lucidumis located in the back of the eye in certain animal species. This reflective membrane gathers in available light and allows such animals to have "night vision" or increased visual acuity in low light situations. This characteristic is typical of nocturnal and deep water species. This also accounts for the "flashback" when you take a flash picture of a pet.
