That is related to their past history. Many galaxies have undergone collisions with other galaxies; this takes out most of the interstellar gas, and the galaxies can no longer form new stars. If I remember correctly, such galaxies will change into elliptical galaxies.

The shape of a galaxy is primarily determined by its rotation and gravitational forces. Spiral galaxies, for example, have well-defined arms due to the rotation of their stars and gas. Elliptical galaxies have a more rounded shape due to the random motion of their stars.

it tells you if it is old, new, what it contains-spiral galaxies have old stars at center, new, bright stars and lots of gas and dust on the arms
elliptical gallaxies have old stars and not lots of dust and gas
irregular galaxies have lots of dust and gas
