peculiar galaxies

Galaxies that do not conveniently fit into the regular classification schemes of normal galaxies. These comparatively rare objects include active galaxies, starburst galaxies, Markarian galaxies, interacting galaxies, single irregular or disturbed galaxies, dwarf galaxies, ring galaxies, and spiral galaxies with peculiar spiral arms or even with one or three arms.
