This is a depiction of the Alien (also known as a Death Angel) seen in the film The Quiet Place, directed by John Krasinski. There is, unfortunately, a lack of original art in relation to these monsters, and so the best I was able to find and give cited credit, was this art depicted above. That is not to say however, that it is a bad depiction. Indeed, it is quite accurate and gives a fantastic representation of the armored head opening up in order to listen for sounds. This is the best description that I was able to refer to in describing how the carapace of the Ghaalb would move.
