Visual perception plays an important role in the animal kingdom, most importantly for the identification of food sources and avoidance of predators. For this reason, blindness in animals is a unique topic of study. In general, nocturnal or subterranean animals have less interest in the visual world, and depend on other sensory modalities. Visual capacity is a continuum, with humans falling somewhere in the center. ==Totally blind species== *Some moles (animal) The Star-nosed Mole can detect, catch and eat food faster than the human eye can follow (under 300 milliseconds).〔(Marsh-dwelling mole gives new meaning to the term 'fast food' )〕 *Sinopoda scurion (Blind Huntsman Spider) The first eyeless huntsman spider to be discovered. Blind animals include the blind cave fish and cave crickets, the Texas salamander, blind flatworms, eyeless shrimp, eyeless fish, cave beetles, cave crayfish, and some bristletails, isopods and copepods. Some animals live only in caves - they are called troglobites (meaning 'cave dwellers'). These animals are adapted to life in the dark.
