Are bats blind??????????????????

Question

Discuss.....

Answer 1

No. They have eyes and can see quite well.  

Answer 2

Absolutely NOT.  Some species have extremely small eyes, but none are blind.

They are able to manuever around in the dark of their caves, or at night mainly with their echo-location, which is similar to sonar.  This is accomplished by them sending out a very high pitched clicking or screeching sounds from their mouths, throats, or noses, and picking it up again as it bounces off their prey or other obstructions and ricochets back to their fantastic ears.  This sound is often beyond human hearing.

There are hundreds of species of bats throughout the world.  Most feed on insects, but others feed on fruit, reptiles, other bats, flower nectar, etc.  Did you know that the bats of the world feed on "tons" on insects every night.  We could not survive without bats.  There are "only" two species of Vampire Bats, and rarely do they bite humans.

Bats are wonderful creatures, and really help in a big way to keep our planet healthy and strong.

Bats have been persecuted by ignorant, stupid, and fearful humans since prehistoric times.  It is now time to stop harassing these wonderful animals and really appreciate what they are and what they do to help this planet.

Answer 3

they are as blind as blind can be.They hear to know where they are going

Answer 4

NO!

Bats are not blind and many can see very well.  Insect-eating bats depend on sound and very good hearing to find food and to get around in the dark.  

Answer 5

No, bats aren't blind. All bats can see, although some species aren't exactly eagle-eyed.

While scientists believe smaller bats don't see in color, many species get around amazingly well in the dark. Some bat species have the added advantage of echolocation -- the ability to bounce sounds off an object, including prey, to determine its size, shape, and location.  

Answer 6

No.  End of discussion.

Answer 7

No. They have eyes and they can see. Just not very well.

Answer 8

not all are, for example the fruit bat could not use ecolocation to find fruit. But most carnivorous bats are nearly blind or blind

Answer 9

They have eyes, but don't function well at night.

They use echolocation to find they're way during night

With the help of the moonlight, they could see a little,

but just enough to see little insects as food

well, they are nearly blind

but can sense ultraviolet light

they're sense of smell and touch are pretty sharp too.

Answer 10

yes they are, they have ecolocation to see where to go

Answer 11

Bats are not blind. Like many animals, they are born blind, but gain eyesight from the time they are seven to nine days old.

The saying, "blind as a bat," probably arose because of the way bats fly around, darting here and there at night. Actually, the bat is hunting insects, which people cannot see in the dark when the bat is flying about.

Bats are night creatures. Most come out only at night to hunt. Although they can see reasonably well, they are not equipped with the special eyesight possessed by other night-hunting animals such as owls and cats. Instead, bats fly and guide themselves in the dark by means of a sonar system.

This is how the bat's sonar system works. As the bat flies, it emits a high, squeaking sound, unable to be heard by human ears. As the sound travels outward, it hits objects and bounces back. These sound waves tell the bat where objects are so they can be avoided. This method of locating objects is called echolocation. Bats fly safely at night by using their ears, not their eyes.

During World War II, a special army unit began training bats to carry bombs into cracks and crevices of enemy buildings. The war ended before the project was ever put into operation!

also some say that:

No, bats aren't blind. All bats can see, although some species aren't exactly eagle-eyed.

While scientists believe smaller bats don't see in color, many species get around amazingly well in the dark. Some bat species have the added advantage of echolocation -- the ability to bounce sounds off an object, including prey, to determine its size, shape, and location.

The Bat Conservation International reports the echolocation of a fishing bat is sophisticated enough to detect a minnow's fin as fine as a human hair sticking up just 2 mm above a pond's surface. Those of us with LASIK should be so lucky.

So saying you're "as blind as a bat" without your contacts isn't really an admission of poor eyesight. It's just an idiom dating back hundreds of years. Though they may be as hungry as a horse, as quiet as a mouse, and as happy as a clam, bats aren't, well, as blind as a bat.

Answer 12

Although the eyes of most microbat species are small and poorly developed,leading to poor visual acuteness or clearness,it is incorrect to assume that they are blind.Vision is used as an aid in navigation especially at long distances beyond the range of ecoholation.
