The two most common shapes for galaxies are a spiral, or an ellipse (circle or oval). All other shapes are considered uncommon.
Spiral galaxys because they represent new stars within the galaxy, and new stars are born very often.
Spiral m sometimes with two curved tails.

The three different types of galaxies are the Spiral galaxy, the Elliptical galaxy, and the Irregular galaxy. Spiral galaxies are obviously in the shape of a spiral, elliptical galaxies are shaped as an ellipse, or a flat circle, and irregular galaxies can be any shape.
Galaxies may have any of four general shapes. Elliptical galaxies show little or no structure and vary in general shape from moderately flat and round or oval to spherical. Spiral galaxies have a small, bright central region, or nucleus, and arms that come out of the nucleus and wind around, trailing off like a giant pinwheel. In barred spiral galaxies, the arms extend sideways in a short straight line before turning off into the spiral shape. Both kinds of spiral systems are flat. Irregular galaxies are usually rather small and do not have a symmetrical shape.
historically, galaxies have been classed or categorized according to their apparent shape (usually referred to as their visual morphology).
You can also distinguish them by the types of stars - older stars versus younger stars, and stars of different "metallicity".
Spiral .
Yes, galaxies can be any size and shape.
oval
Irregular galaxies have no discernible shape.
Because irregular galaxies have no definite shape.
The Clouds of Magellan are known as irregular dwarf galaxies. They are relatively small and do not have a specific shape.
Yes, peculiar galaxies are strangely shaped.
they are classified by there shape .
fartlike
the types of galaxies are barred, irreagular, spiral, and a shape like an hourglass.
spiral, elliptical, and irregular. The only differences are shape. Elliptical galaxies are shaped like an ellipse, spiral galaxies like a spiral or pinwheel, and irregular don't have a uniform shape
