Dwarf and Low Surface Brightness (LSB) galaxies are the most numerous type of galaxies in the local Universe. However ubiquitous they are, their properties remain widely unexplored. Dwarf galaxies range from Ultra Compact Objects (UCO), Dwarf Ellipticals (dE), Dwarf Spheroidals (dSph) to Dwarf Irregulars (dIrr) and are generally of low surface brightness. In this paper we focus on the relation between these objects and galaxy clusters. The discussion is centered on three main issues, the faint end of the cluster luminosity function, segregation of dwarfs in clusters and the dwarf galaxy – cluster dynamical state connection. A further analysis of the population and clustering properties of dwarf galaxies in clusters require better statistics. While concluding, we present, as well, future prospects on how to measure distances to dwarfs using the surface brightness fluctuation method so as to increase the number of confirmed dwarf member galaxies in more distant clusters.
