This dude has a god damn worm in his eye!
These are mango worms similar to maggots, they feed on proteins in tissues found under the skin of dogs, cats, goats. Like Botfly's, they are transferred under the skin by mesquitoes that have come in contact with the eggs, they grow, manifest, and have to be removed or they could breed more thoroughly, as seen here.
Are you squeamish? If not, then check out this chicks eye parasite.
WTF was living inside that mantis???
When a mud puddle forms the worms will come out to play.
If you're gonna fail you may as well go out with some style.
Damn that's pretty nasty. Imagine if you had one of those inside of you. It's a horse hair worm.
Make sure you look in the package before you buy!
