Object name: ARP087
Arp 87 is a pair of galaxies in northeast Leo about 335 to 340 million light-years away. Arp put it in this category of spirals with large high surface brightness companions on arms." His comment is more telling. It reads "Arm appears wrapped around cylindrical companion." His was a pure descriptive narrative. He left it to others to explain what was going on. In this case, we have a pretty good idea and it's quite interesting. This appears to be the formation of a polar ring galaxy caught in the act of formation. The companion is well underway of becoming a polar ring galaxy.
