WebSome viral capsids are simple polyhedral “spheres,” whereas others are quite complex in structure. In general, the shapes of viruses are classified into four groups: filamentous, isometric (or icosahedral), enveloped, and head and tail. Filamentous viruses are long and cylindrical. Many plant viruses are filamentous, including TMV.
