It's from a stream benthos sample from France...I was thinking in some parasitic worm as Trematoda, but could not find anything similar...hope you can help me,
thx
Andrés
Hola Andrés, un saludo. Ostras, porque dices que es un gusano, porque realmente tiene un aspecto de alga... Lo siento, ni idea
hola Andrés, creo que son nematodos mermítidos. Los he visto muchas veces saliendo del interior de larvas de invertebrados, al fijar la muestra. SOn parásitos internos.
un abrazo!
Gracias a compañer@s por vuestra ayuda, de momento creo que me quedaré con los Nematoda: Mermithidae que sugiere Carmen,
abrazos!
Andrés
Hola Andrés,
Yo opino igual que Juan, tiene pinta de 'Schistosoma', los gordiacea como sugiere Andrés son mucho más largos y de grosor constante por lo menos los que he visto yo. Si consigues saber lo que es no dejes de contarlo!!
Saludos, Fon.
Hello all,
Andrés, if this "creature" is an animal, I think it may be a worm belonging to the group of "NEMERTS".

As I commented earlier 8in Spanish) Carmen Zamora-Muñoz oppinio is correct. They are round worms (Nematoda: Mermithidae). Any student of General Zoology should recognize the Phyllum Nematoda. As C.Zamora-Muñoz commented. Mermitids have part of its life cycle as parasitics of invertebrates and they are very often found into larval stages of aquatic insects, and easily visible. Of course they can not be Schistosoma because these live inside blood vessels, with a totally different morphology and the size is much smaller. Also Nemertina are very very different!.
Tiene pinta de una semilla recien germinada! pero vaya Vd a saber.
To be able to be sure and clarify without any doubt. Just mount it on an slide and visualize the internal structures under the microscope!
Without knowing the magnification this is just a guess but it might be a horsehair worm.
Well, thank you very much again for all your messages . Finally I examided the "creatures " under a microscope, as Javier suggested. I think Diego was right , they seem newly germinated seeds.
Here you have a photo of the thinnest part, because everything else was very opaque. Of course , no internal structures...I apologize for not doing this before asking,
best!
Andrés
