don;t tapeworms require an intermediate host to transmit?
I could be wrong but I don;t think it would be a problem for a ray to eat a fish with a tape worm like this in it.
im not an expert on worms at all.... but to me... that looks like an earthworm someone squished up all the insides out, and cut a rosy red to make a point...

The adult tapeworm attaches to the small intestine of man, matures and sheds eggs that pass in the feces.
The egg continues its development in water, eventually producing a ciliated embryo, called a coracidium, which hatches and becomes free-swimming.
When the free-swimming coracidium is eaten by a small crustacean (a copepod), it develops into a procercoid larva that is now capable of infecting fish.
When plankton-feeding fish eat infected copepods, the procercoid is released and develops into another larva, called a plerocercoid that migrates to the muscle or visceral organs of the fish.
