Space-Bat

Space-Bats, a.k.a. Giant Space Bats, are large flying organisms that apparently live in space and are considered a threat to cosmonauts.

Biology
These creatures can live in a cold vacuum, likely indicating a body covered in a form of exoskeleton or full-body armor plating. They have green-hued skin, a pair of large eyes, moderately-sized ears, large wings, a snapping maw, a long tail spiny tail and clawed feet. Their large wings seem to be used to help them swoop in and grasp organisms up to at least the size and weight of a human youth and take off with them quickly.
