The subject of joint research is the photometric, spectroscopic and morphological investigations of the galaxies in SHCGs for an understanding their properties (the morphology, dynamics, chemical abundance as well as evolution effects). CCD photometric and spectroscopic observations of the galaxies in SHCGs have been taken out with the 2.6 m telescope at the Byurakan Astrophysical Observatory during 1998-2000. The data reduction procedure was made using the MIDAS, IRIS, SIPL programmes at the IAA. Some compact groups contain a high fraction of galaxies with morphological or kinematical peculiarities, and starburst or AGN activity. According our preliminary data about 7-10% of member galaxies in SHCGs are emission-line galaxies. Possibly, because of their large distances (0.04 < z < 0.16) with respect to the Hickson groups (z median ~ 0.03) SHCGs are intermediate in physical properties between classical compact groups (i.e. Hickson groups, Rose groups, south compact groups) and clusters of galaxies.
