"Bottom mines are very difficult to detect, and to help with ensuring that none were still around Umm Qasr, the U.S. Navy flew in two of their mine hunting dolphins. The only problem they expect to encounter with the dolphins is hostility from local dolphins. Like wolves and bears, dolphins are territorial and will try and chase away any strange dolphin they find in their normal feeding territory." (The story, dated today, is titled "SURFACE WARSHIPS: Iraqi Bottom Mines and Dolphin Turf Battles.")
