Quite likely, otherwise, how would they digest their food?

No, not an adult coral. Coral eggs and larve, yes....but clams have no means of being predators on corals and their digestive systems cannot deal with such input.
Well, clams filter feed, so I don't think they actually have digestive systems at all. I would imagine, with all the stuff floating in seawater, that they simply absorb nutrients out of the brine they filter through themselves.
Clams feed on tiny particles of whatever matter is suspended in the water. They draw the water in through their siphons and strain any particles through a pair of gills. Waste matter is ejected after passing through their digestive systems.
The visceral mass in clams serves as the central region containing most of the internal organs, including the digestive, reproductive, and excretory systems. It is crucial for the clam's survival, as it facilitates nutrient processing, waste removal, and reproduction. This mass is protected by the shell and is part of the overall body plan that allows clams to function effectively in their aquatic environments.
Oh yes, amphibians have digestive systems.
The nervous system of clams often does not include the circulation system. The nervous system does not include the shell or the digestive system either.
The pharynx is part of both the digestive and respiratory systems.
The digestive system provides usable nutrients for the other systems.
The digestive system starts at the mouth.
The digestive system is different from the other human body systems because the digestive system holds food and no other human body system does also the digestive system has organs that none other human body systems have.
