Which living creatures are naturally blind?

Question

Which living creatures are naturally blind?

Answer 1

creatures that live in a cave thier whole lives

there are species of cave dwellers such as: fish, salamanders, crickets, slugs, spiders, scorpions, beetles, snails and many others

also many creatures that live near hydrothermal vents and feed off  the bactieria that live in deep in the ocean, these include fish, crabs, shrimp and worms

also certain burrowing animals such as earthworms and moles  are also blind

but contrary to popular belief, bats can see, just not very well. They do however use echolocation as their main source of sensory information  

Answer 2

worms?

Answer 3

badgers i think

Answer 4

First: bats are NOT blind. Insectivorous species tend to have poorer eyesight and rely more strongly on echolocation, while many species of fruit bat lack echolocative abilities entirely and rely on their senses of sight and smell to find fruit - hence why many cactus fruits (pollenated by fruit bat species) tend to have strong smells and bright reddish coloration.

The only truly blind mammal is the naked mole rat, which possesses mostly nonfunctional eyes covered by skin; it does use light sensitivity by some unknown method to regulate certain body processes, however.

Many molluscs, including almost all bivalves except for scallops, are entirely blind.

Blind species abound in cave environments; there are blind species of fish, such as catfish, as well as blind frogs, blind crabs, blind salamanders, blind centipedes, and I believe blind cave-dwelling swallows as well.

Answer 5

ones that live in subterranean territories, like in cave's and in the deep ocean.

Also white animals that have blue eyes can be either naturally(gentically) Blind or death, this is due to the white gene missing other important parts.

Bats can see by the way.

Answer 11

bats um worms thts all i know of sorry

Answer 12

there are actually some crabs they have discovered in one of those pretty much completely unexplored underground/underwater caves and it had no eyes, so obviously it is completely blind. because there is absolutely no light in these caves they don't need their eyes, so they have evolved into not having any. it takes many thousand years for eyes to de evolve (not sure this is right word) so they have been down in this cave for all that time without anyone ever knowing they were there!!
