The majority of viruses have capsids with either helical or icosahedral structure. Some viruses, such as bacteriophages, have developed more complicated structures due to constraints of elasticity and electrostatics.
Bacteria come in three main shapes: 1) Spherical (like a ball). These are usually the simplest ones. Bacteria shaped like this are called cocci (singular coccus). 2) Rod shaped. These are known as bacilli (singular bacillus). Some of the rod-shaped bacteria are curved; these are known as vibrio.
