Its an old picture ,all data missing
looks like some species of Echiura to me. this would be marine benthos.
what the exact size? is there any hook at their head?
Yes It looks like Echiura speceis when Google d..
Echiura or potentially a Sipunculid if there are rows of small hooks down the thicker part.
Have you dissected it? Sipunculids have the u shaped digestive tract. It that a proboscis?
iSorry but my experience is in agroecosystems Fruticolas insects and forest
Priapulid, maybe?
Does the animal have a relative rigid chitinuous cuticule and a straight digestive tube?
It looks also like an Acantocephalus, a parasite that lives in the intestine of vertebrates.
I think it's a sipunculid. Quite possibly of the genus Sipunculus. S. nudus is a cosmopolitan species and is very similar.
I Think it's a Sipunculid. Maybe Sipunculus. It's very similar in fact, but it´s already dead.
Hello Quddusi; I'm voting with the sipunculid crowd. I wish I could touch it. Best regards, Jim Des Lauriers

There is huge pressure of getting good impact factor on scholars now a days. On the other hand Taxonomy is a very dry subject and the concerned papers can only get citation in same group of organism.
