There are a couple of animals that have no digestive systems (usually a invertebrate)
One of the example is tapeworm ( some kind of parasite that live inside our body). Because tapeworms do not have any digestive system , they must eat food already digested by another animal. They absorb nutrients directly from their skin.
It is possible for the
discovered animal to have no digestive system. An example of this is the
protists. Protists belong to the group
eukaryotes (having their DNA enclosed inside the nucleus). They are not plants,
nimals or fungi but they act like one. They can be in general subgroups such as
unicellular algae, protozoa and molds.
