A fish can have up to three dorsal fins. The dorsal fins serve to protect the fish against rolling, and assist it in sudden turns and stops. 1  In anglerfish, the anterior of the dorsal fin is modified into an illicium and esca, a biological equivalent to a fishing rod and lure.he pelvic fin assists the fish in going up or down through the water, turning sharply, and stopping quickly. 1  In gobies, the pelvic fins are often fused into a single sucker disk. 2  Pelvic fins can take many positions along the ventral surface of the fish.
BP plc, also referred to by its former name British Petroleum, is one of the world 's seven  supermajor  oil and gas companies.P has one of the worst safety records of any major oil company that operates in the United States. Between 2007 and 2010, BP refineries in Ohio and Texas accounted for 97 percent of egregious, willful violations handed out by the U.S. Occupational Safety and Health Administration (OSHA).
In May 2010, BP tried to cap the oil spill in the Gulf of Mexico by plugging the leak with heavy mud. Had it worked, it might have given them some hope of limiting the damage to their reputation. As it didn't, the BP brand name is, more literally than most, mud. BP's CEO Tony Hayward has joined another villain of the collective American psyche, Dr. Samuel Mudd, who is widely reviled for his part in the assassination of President Abraham Lincoln.
