Answer

Brief Explanations:

There are two main types of spiral galaxies: normal spiral galaxies and barred - spiral galaxies. Barred - spiral galaxies have a bar - shaped structure through the middle from which the spiral arms extend. A football - shaped description is more for elliptical galaxies. Irregularly shaped refers to irregular galaxies. Having arms start close to the center is not the defining characteristic of the second type of spiral galaxy.

Answer:

has a bar through the middle from which arms extend
