The most obvious features are the muscles and the glandular canal. Looking more closely I can match the pale foamy nerve cord. The histology in both the images have gaps in the tissue, I suspect that the planarian was not well preserved. Tissue sections must be cut thin enough for the both formalin fixation and tissue processing. In Anatomic Pathology residents have drilled into them that formalin fixation is a slow process. <br /><br />All in all, not a parasite.<br /><br />HPAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-629132641307534690.post-79469610603535649272020-01-21T21:15:16.733-06:002020-01-21T21:15:16.733-06:00Agree with a hammerhead planarian.

The internal morphology from the cross section HE stain suggests that the specimen may have a digestive tract. Overall, this "worm" is not compatible with any platyhelminthes we are familiar with, it rather is suggestive with an incidental find of possibly a slug.<br />Florida Fan Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-629132641307534690.post-91854462696236885912020-01-20T20:46:41.682-06:002020-01-20T20:46:41.682-06:00Do you know the location of host?
