These specimens were found on stomachs of eagle rays.
Pictures are attached on a Microsoft Word document.
I am just guessing, but is there any chance that the first picture shows juvenile Lingula or Glottidia specimens, perhaps half-digested so that the shells are gone?
I don't see any anatomical features in the oval body. If they indeed are inarticulate brachiopods, there might remain a recognizable lophophore near the end opposite the "pedicle".
Dear Francisco,
Although I am not an expert here (so you have to regard this comment as guesswork), most of the photographs remind me of Cephalopods, most likely various species of Teuthoidea (Fig. 2,3,6,7,12,13,14,15). It looks like partly digested bodies, gladius, beaks, and teethed rings from the tentacle suckers. The spherical objects (16,17,18) I believe may be eye lenses, probably from cephalopods, too, or maybe fish. The piece of flesh in Fig. 11 is part of a fish, maybe elongated, and apparently with red muscle, so that could limit your search down. Does the object in Fig. 3,4 have remnants of cuticle? Then it could be part of a crustacean, but I am not sure. If the object in Fig. 1 is round and soft, could it be Sipunculids?
To the other objects, I have no clue what they were.
For determining the Cephalopods, maybe these links might be useful:
Good luck with your determination, and best wishes
Paavo

Dear Francisco,
I'm not working with marine species but I agree with Paavo in most of his opinions. Many of the rests could be from Cephalopoda, images 3-5 are probably crustacea (Decapoda) and the sphaerical objects are very similar to eye lens but from fishes. The piece of flesh is a portion of a fish, is it flat laterally? In this case it could be a kind of "pez sable" (in English I think the name is something like "largehead hairtail"
Best regards
Maria
I just had another look at the pictures. In Fig. 8, I didn´t recognize before the ragged, broken edge at the bottom, indicating it is some hard substance. In that case, I would say it resembles a crushed and flattened barnacle (Crustacea - Cirripedia)
The black objects on pages 12-15 are likely to be jaw parts from polychaete worms, perhaps in the family Lumbrineridae or Onuphidae.
The spherical objects on pages 16-17 look a lot like small Sphaeromatid isopods.
Cheers

Thanks you all! I'm working trying to fnd what species they are. Fig1 seems like a brachiopod as Enrico said, But I was told it may be a Hirudinella.
Fig. 2. Could it be Trematoda?
Fig 3.,4,5, Ogyrides sp? I say this because of the large eye peduncle, seem huge but the telson makes me get confussed (the form).
Fig.9: I guess it could be egg from that crustacean
Fig. 6. I have no idea what it may be.
Fig. 7. Those are the radula of Dosidicus gigas, but it is not so difficult for a eagle ray to eat them? I have found also sea bird feather; maybe it is due to fishing activities.
Fig. 10: Nematodes? polychaete?
Fig.11. I guess it is Anchovy, there are tons of this species
Fig. 12-15: I don't have a clue
Fig. 16-17: Eye lenses, it thought it was a kind of cysts 'cause i found one on the abdominal cavity of a fish (Fig. 18).
Please help me out to get these species identified.
