That is how feces looks like when you do bowel cleansing or parasites cleansing ...
You have to wash things first!
To find parasites, worms, you will have to have glows on ... and start washing and searching for details ....
Like, take all feces into a large jar with water, shake it well, and than look for parasites.
If they are very small worms like pinworms, you may have problems finding them.
Worms usually have very perfect, hydrodynamic bodies, very symmetrical, the left side of the body looks the same as the right side, like in most animals, like maggots, like earthworms, like caterpillars, like snakes.
You can not see small worms easily inside feces, unless you have a very large number of them.
You can see very large worms like Ascaris
Lumbricoides, which is easy to see due to its size (30 cm, looks like white earthworm).
