Description

Se trata de un gusano o Nematodo (?) desconocido para mi. Parece un alambre, de color negro, creo que con algunos anillos casi imperceptibles, puede permanecer inmóvil, pero se mueve dentro del agua. dificil reconocer incluso cual es su parte anterior y posterior.. Lo encontré en el piso, en un charco de agua con tierra.. el palillode referencia mide 4.5 cm

Description

I happened to accidentally step on a beetle while looking for moths and felt really bad. Then this Horsehair Worm started emerging from the beetle so I guess it was doomed already.

If there is any way to narrow down the ID I would appreciate the help.

Description from Wikipedia

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. They range in size in most species from 50 to 100 centimetres (20 to 39 in) long and can reach in extreme cases up to 2 metres, and 1 to 3 millimetres (0.039 to 0.12 in) in diameter. Horsehair worms can be discovered in damp areas such as watering troughs, swimming...
