Bats are a characteristic animal of Halloween, such that rendering one as a skeleton to make it scarier seems unnecessary, even redundant. Yet we have the bat skeleton, available for $31.45 from DHgate.
It has external ears presented as bony elements of the skull, which is a common problem with plastic Halloween mammal skeletons.
What’s even stranger is the depiction of the bones that make up the wings. A real bat has one digit in each wing that is outside the wing membrane, and four more digits that support the wing membrane. This fake bat has only three digits in position to support the wing membrane. And the metacarpal of the uppermost wing digit has been replaced with what are apparently meant to be a radius and ulna. (That’s the weird double bone along the top of the wing in the plastic skeleton). In reality the radius and ulna are part of the arm, and thus closer to the body, although in bats the ulna is greatly reduced.
If you find all of this confusingly technical, you can check out correct bat skeletal structure here.
