Peculiar galaxies are a heterogeneous group with irregular and unusual shapes, structures, and features, often resulting from interactions or mergers. No specific example, as they are defined by being atypical.

Spiral galaxies have rotating, flat disks with central bulges and spiral arms, often hosting younger stars and significant star formation. Examples: Milky Way, Andromeda (M31).

Irregular galaxies lack a distinct shape or structure, often chaotic in appearance, with active star formation. Examples: Large Magellanic Cloud, Small Magellanic Cloud.

Dwarf galaxies are small galaxies composed of up to several billion stars, which is small compared to our Milky Way galaxy. Examples: Draco Dwarf, Sagittarius Dwarf Spheroidal.

Ring galaxies are characterized by a ring-like appearance, often formed as a result of a galactic collision. Examples: Hoag's Object, the Cartwheel Galaxy.

Elliptical galaxies are oval-shaped with smooth, nearly featureless brightness profiles, made mostly of older stars with minimal star formation. Examples: M87, M49.

Seyfert galaxies have bright nuclei and are a subset of Active Galactic Nuclei (AGN), noted for their strong emissions and variability in brightness. Examples: Messier 77 (Cetus A), NGC 4151.

Barred spiral galaxies feature a central bar-shaped structure composed of stars, with spiral arms extending from its ends. Examples: Milky Way (possibly), NGC 1300.
