18. Moth Larva

It is easy to misspell “moth” with “mouth” and accidentally adding a single letter could mean the difference between seeing nature at its finest, or at its worst. Typing “mouth larvae” instead of “moth larvae” on your Google search bar will bring out images that give a whole new meaning to creepy. Photos of maggots crawling between human teeth, as well as inside animal mouths are the stuff of nightmares so make sure that you always check your spelling before hitting enter when searching.
