Crawlers are some of the most disturbing zombies in pop culture. From the brilliant half-bodied redhead who came in the window in Return of the Living Dead to the half creature Rick encounters in the premier of The Walking Dead. The very fact that large parts of their bodies are missing is freaky as all get out.
The danger posed by these nasties is that they could be in a lot of places you wouldn’t expect, small crawl spaces, under cars, hidden in tall grass where you can’t see them. Fortunately with large parts of their bodies gone, their mobility is seriously cut down and it becomes a lot easier to take them out.
I noted above that this crawler’s hair is falling out but that’s more of a general rule for zombies as they go along. Though crawlers may be fresh, a lot of them have been around for a while and the loss of their lower halves has happened over a period of time. Any zombies that have been around for a while are likely to have thinner hair as whatever gets pulled out or falls out isn’t going to be replaced by fresh hair growth. This is one of a long list of symptoms you’ll notice for older zombies like a larger number of open cuts and scratches, the fact that they’re dirtier and their teeth are much worse for wear.
