The difference is in the shape, as can be guessed by the name.
An irregular galaxy. See related question.
There are the the spiral, elliptical, and irregular galaxy formations.
There are three main types: spiral, elliptical and irregular.
It doesn't really work that way. The types aren't exactly related to size, but rather to shapes. Dwarf galaxies of course are the smallest; but other than that, a spiral galaxy can come in different sizes; so can an irregular galaxy or an elliptical galaxy.

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.
I think the least common is elliptical or irregular..
An irregular galaxy is a galaxy that doesn't have a specific shape like a pinwheel or an elliptical galaxy.
It is known as an irregular galaxy. A few different Classifications are : Irr L (some structure) Irr LL (No visible structure) Also Dward Irregulars : DL DLRRS (Low Metallicity)
Spiral Galaxy. Your Welcome =)
Generally, an elliptical galaxy is the oldest, a spiral galaxy is mid life and an irregular is fairy new. However, this is generally. An irregular galaxy can be formed from the merge of two elliptical galaxies - so it's not fool proof.
there are 3 types of galaxies. 1.spiral 2.elliptical 3.irregular the main galaxy in our universe would be a spiral galaxy
A dwarf galaxy by virtue of it's name will be smaller than a "normal" galaxy.
B.) A giant elliptical galaxy
