Butterflies bats and birds all have wings that allow them to fly butterfly wings however do not have bones like bat and bird wings do

The wing of butterflies compared to that of birds and bats show analogy.

Explanation:

In the field of biology, analogy can be described as organisms which might have the same function but different biological origin. As we know, all of the flying animals have wings to fly. But all these organisms might not have a common origin. When comparing bats and birds to butterflies, we can see that butterflies have two pair of wings whereas, bats and birds have a single pair. Also, there are many other differences like the wing of a bird has feathers while butterflies do not have feathers.

one characteristic that is shared by all is a soft body. many

of these invertebrate animals also have an outer shell to protect their

body. oysters, clams, snails, and mussels are all mollusks. so are octopuses, squids, and slugs. mollusks live on land and in freshwater.
