Difficult to "PIN"-point the exact species of these nematodes without any mention of their size...

Enterobius vermicularis adult
Enterobius vermicularis - long pointed tail of female worm highlighted in 3 image. Appendix infestation has been documented to lead to accute appendicitis symptoms (PMID: 19061517).
For sure they are pin worms, that’s when there’s a necessity for a dissecting microscope. Ascaris are too big to magnify. Everyone pin them down right away.

Enterobius vermicularis adult female larva, probably gravid and full of eggs. Awesome pics. Neat to see
