Baccapulmons have a long, elongated body. They have projections of bone on the skull that resemble horns.
Baccapulmons eat mainly meat, but will eat plants and fruits as well.
These creatures have a tendency to collect minerals. They can also change color. These features are also used by the Terrorteeth, which raises the possibility that these two genera are particularly closely related (all dolosids have the ability to change color, but not all collect minerals).
