De Vaucouleurs Atlas Description:
The background starlight is very smooth in this strange object. In one interpretation, the galaxy has a broad bar with two open spiral arms; this is the basis of the RC3 type. However, this interpretation is not viable because of the odd dust lane. Also, a 2MASS image (Jarrett et al. 2003) shows a peculiar morphology that does not resemble a barred galaxy. The presence of tidal debris indicates that NGC 3718 has suffered a major interaction. All features are unusual.
