Which of the following is a mammal that can fly?

Among all mammals, bats are unique because they are the only group capable of true flight. Unlike birds or insects, whose wings are made of feathers or chitin, bats have wings formed from a thin membrane of skin called the patagium, stretched over elongated finger bones. This structure allows them to maneuver with great agility in the air, even more precisely than most birds.

Bats belong to the order Chiroptera, which literally means “hand-wing,” reflecting the fact that their wings are essentially modified hands. This adaptation provides them with the ability to generate lift and sustain flight, making them distinct from all other mammals, which may glide but cannot truly fly. For example, flying squirrels and colugos can glide from tree to tree, but they lack the anatomical structure for powered flight.

Comparing with the given options:

• 
  

  Ostrich is a large flightless bird, not a mammal.

  
  


• 
  

  Peacock is also a bird, known for its colorful tail feathers, but it is not a mammal.

  
  


• 
  

  None of these is incorrect because bats do indeed exist as flying mammals.

  
  

Bats play a crucial role in ecosystems. Many species feed on insects, helping to control pest populations naturally, while others are pollinators or seed dispersers, making them vital for plant reproduction and biodiversity. Despite their ecological importance, bats are often misunderstood due to myths and misconceptions.

Biologically, bats also have fascinating traits such as echolocation, which allows them to navigate and hunt in complete darkness by emitting high-frequency sounds and interpreting the returning echoes. This ability places them among the most advanced mammals in terms of sensory adaptations.

In conclusion, bats are the only mammals that can fly, setting them apart from all other animals. Their specialized anatomy, ecological importance, and unique behaviors make them one of the most extraordinary members of the animal kingdom.
