In the photo is a pig worm, whose microscopic photograph was made by Theresa Zgoda from the Rochester Institute of Technology in New York.
With this photo she won fourth place at the annual 2017 Nikon Small World competition.
A glutta in human scurvy can come when eating insufficiently heat-treated meat in which eggs or larvae can be caught. The larva develops when it comes to the small intestine in which it can live for years.
The glutens are hermaphrodites, which feed through the surface of their body.
They can reach a length of 25 meters, although they are usually five times shorter.
