We observed a white adult male killer whale (Orcinus orca) on 7 August 2000 off the north side of Adak Island, Aleutians. An open saddle and a rounded dorsal fin tip suggest that this whale belongs to the fish-eating (“resident”) ecotype. A circular scar matching a cookie-cutter shark (Isistius sp.) bite mark suggested that the animal originated in warmer waters. Photographs and description provided here should enable individual identification should this animal be seen again.

A preliminary assessment of mitochondrial DNA restriction patterns in the killer whale (Orcinus orca) was conducted using 10 captive North Atlantic killer whales from the southeastern coast of Iceland, a captive-born offspring of one of these whales, and 9 North Pacific killer whales. No restriction pattern variation was seen among these whales, using the enzymes BamH I, Bgl II, Hinf I, Kpn I, or Pvu II. Restriction pattern variation was found using the enzyme Hae III. This restriction endonuclease distinguished the North Atlantic killer whales (type 1) from the North Pacific killer whales. The North Pacific killer whales were further differentiated into two groups: those originating from the "resident" communities of the Vancouver Island region (type 2), and those from the "transient" community of Vancouver Island, as well as those stranded along the Oregon coast (type 3). The observed Hae III restriction pattern differences suggest that mitochondrial DNA analysis will be a valuable technique for investigating regional and local distributions of maternal lineages among killer whale pods, especially in the North Pacific.

Abstract Killer whales, Orcinus orca, were first reported off North Carolina by naturalist John Lawson in 1709, and during the 20th century were documented from North Carolina eight times in the scientific and popular literature. The most recent confirmed sighting of killer whales off North Carolina was in the spring of 2011. There have been no reports of killer whale deaths from North Carolina. There has been only one killer whale stranded along the North Carolina coast, with the animal being alive when it was returned to the sea. All sightings have been in the waters of the Atlantic Ocean, none on the west side of the Outer Banks in the waters of Pamlico or Currituck sounds. Only three confirmed reports are from nearshore waters, while the rest were spotted more than 20 km offshore. Orcas are most frequently reported from the waters off the Outer Banks from Cape Lookout north to the Virginia border. A 200 yr gap exists in the historical record of killer whales from North Carolina.

Male Killer

On 3 May 1988, we observed a group of killer whales that pursued, killed, and partially consumed a Bryde's whale in the northern Gulf of California, Mexico (31°01′N, 114°15′W). The attack was observed from 06:54 to 08:53 while circling in a single-engine aircraft at an altitude of 160 m. The group comprised about 15 killer whales, including two adult males and at least two calves. Females and (or) subadult males pressed the attack most intently. The killer whales tore skin and blubber from the right flank of the Bryde's whale, and on 11 occasions the killer whales swam onto the head or back of the Bryde's whale, which hindered its breathing. The respiration intervals of the Bryde's whale were short and irregular, and blow rates differed significantly from those of undisturbed Bryde's whales. Fatiguing the whale may have facilitated an easier kill by asphyxiation. After the death of the Bryde's whale, the two adult male killer whales surfaced slowly about 200–300 m away from the remainder of the group, which presumably fed on the submerged Bryde's whale carcass. Two days later, the drifting Bryde's whale carcass was located. A large wound was visible on the abdomen, and sections of the lower jaw had been removed. Like those of canids and some felids that hunt cooperatively when preying on ungulates, attacks by Orcinus orca exhibit coordination of activities and efficiency in dispatching prey.
