Bat wings are homologous structures because they bear structural similarity to the limbs of other organisms and analogous structures because of their functional similarity to other organisms' wings. Bat wings are also an example of convergent evolution.Know More
Bats belong to the taxonomic order Chiroptera, which is a combination of the Greek words for hand and wing. Bat wings are homologous with other mammalian forelimbs, including the human arm and hand. This means that bat wings share structural similarities with the limbs of much more distantly related species. A bat's wing exhibits a humerus, radius, ulna, metacarpals and phalanges. In comparison to many other mammals, a bat has a smaller ulna, more rigid wrist and longer phalanges, and a membrane of skin covers the entire limb. The bat's wing membrane is an extension of the skin of the body and consists of both epidermal and dermal layers.
Bat wings are analogous to bird wings. Analogous structures exhibit similarities in function even though, structurally, they are quite different. While a bat's fingers provide support for the wing membrane, a bird's digits are fused together and support the feathers. Analogous structures arise due to convergent evolution. In convergent evolution, unrelated species evolve similar structures because they utilize like behaviors or fill similar niches.Learn more about Bats
There are several options for catching a bat that include using a butterfly net or towel, trapping it underneath a bucket or similar item or using leather gloves to grab it. Leather gloves are not typically recommended unless the person is highly experienced, as a bat will try to bite when it is being grabbed.Full Answer >
Bats can walk, albeit clumsily. Their bodies are so highly adapted for flight that their legs serve mostly as attachment points for the surface of their wings. Crawling on the ground requires a lot of energy from bats because their leg bones are poorly designed for moving in that way.Full Answer >
Vampire bats feed solely on the blood of other animals, usually on cattle and horses. However, vampire bats do not suck blood. With their razor-sharp teeth, they make small incisions, usually in a sleeping animal. Then they lap up the blood, roughly one teaspoon, without ever waking up the animal.Full Answer >
Although no living bats are completely blind, most bats rely on sounds to find their prey at night. Known as echolocation, ultrasonic sounds are emitted by bats that bounce off of other objects. By hearing these echoes off of objects around them, bats can create an internal map that allows them to navigate and capture food.Full Answer >
