This is a list of animals that can see in the dark. All animals that are able to visualize things at night are called Nocturnal Animals. While some animals can see in an absolute darkness even in a moonless night (like snakes), others become active in twilight--either way they are all nocturnal. Just to let you know that some of these animals might be crepuscular i.e. they come out in dusk but still they show nocturnality in their behavior which is why they are included. Prominent among the crepuscular animals is lion.
