What is the difference between Nematoda and Nematomorpha?
The main difference between Nematomorpha adults and Nematoda adults is the degenerate gut in the Nematomorpha. The role of the adults is not feeding, but reproduction and dispersal, and they have a featureless body, as the name, hair worm, suggests.
Can a horse hair turn into a snake?
If a single horsehair is placed in water, in the summer time, it is believed to turn into a snake. This notion probably arose from the fact that long hairlike worms, said to mature in the intestines of grasshoppers, are sometimes seen in watering troughs and roadside pools.

How many species of Nematomorpha are there in the world?
About 351 freshwater species are known and a conservative estimate suggests that there may be about 2000 freshwater species worldwide. The name “Gordian” stems from the legendary Gordian knot. This relates to the fact that nematomorpha often tie themselves in knots.
How big does a Nematomorpha horsehair worm get?
Nematomorpha. Most species range in size from 50 to 100 millimetres (2.0 to 3.9 in) long, reaching 2 metres in extreme cases, and 1 to 3 millimetres (0.039 to 0.118 in) in diameter. Horsehair worms can be discovered in damp areas, such as watering troughs, swimming pools, streams, puddles, and cisterns.
What kind of worms are similar to nematode worms?
Nematomorpha (sometimes called Gordiacea, and commonly known as horsehair worms or Gordian worms) are a phylum of parasitoid animals superficially similar to nematode worms in morphology, hence the name.
How did the Nematomorpha get its name Gordian Knot?
The name “Gordian” stems from the legendary Gordian knot. This relates to the fact that nematomorphs often tie themselves in knots. Nematomorphs possess an external cuticle without cilia. Internally, they have only longitudinal muscle and a non-functional gut, with no excretory, respiratory or circulatory systems.
