"Are all baby flukes the red/pink chunks or tomato skins?"
The babies look like transparent tadpoles and transparent slices of a big seed. I have also seen globs of mucus with lots of black specks in them. Unfortunately, I have babies, teenagers (green globs that sometimes have a brown or red hue), red and brown blobs that grow into big grey flat monsters. And, of course, the curled-up tomato skins. And they are just the liver flukes.
