While killer whales can be found around the world, they are much more common in highly productive areas of cold-water upwelling; including the Pacific Northwest, along northern Norway's coast in the Atlantic, and the higher latitudes of the Southern Ocean.

In addition to being found in colder water, killer whales also have been seen in warm water areas such as Florida, Hawaii, Australia, the Galapagos Islands, the Bahamas, and the Gulf of Mexico and more temperate waters such as New Zealand and South Africa. Such sightings are infrequent, but they do demonstrate the killer whales' ability to venture into tropical waters.

Rarely, killer whales have been seen in fresh water rivers around the world such as the Rhine, the Thames, and the Elbe. One even traveled some 177 km (110 mi.) up the Columbia River in pursuit of fish.

For the most part, killer whales in the wild are visible only when they are at the surface, so it is inherently challenging to document and study whale behavior.

Ecotypes of killer whales can be very different from one another in diet, appearance, dialect, and genetics. Experts use caution when generalizing about killer whales, knowing that the different ecotypes of killer whales that have not been as well studied may be quite different from the eastern North Pacific resident whales.

Globally, killer whales appear to have an extremely diverse diet. Yet, individual ecotypes or populations are often extremely specialized. In many parts of the world, killer whales prey on fishes or marine mammals, but not both.

Killer whales are carnivore marine mammals, so their diet is full of meat gotten by hunting several species in their habitat. Since there are several ecotypes of killer whales, their eating habits are closely linked to the geographical area where they are located and with their population. Thus, the orcas in a specific region can specialize in hunting and consumption of a particular prey.

Orcas feed on a wide variety of prey, from small schooling fish to large baleen whales. These cetaceans are powerful predators, which are not intimidated by large, or bulky animals, and are known to be able to attack even sharks.

Adult male killer whales are larger overall than their female counterpart including features such as pectoral flippers, dorsal fins, tail flukes, and girth.
The largest recorded male killer whale was 9.8 m (32 ft.) in length and weighed 10,000 kg (22,000 lb.) The largest recorded female was 8.5 m (28 ft.) and weighed 7,500 kg (16,500 lb.).
Data from Icelandic killer whales (North Atlantic type 1) indicate that an average-size male is 5.8 to 6.7 m (19-22 ft.) long.
The general body shape of a killer whale is roughly cylindrical but tapering at both ends. This characteristic fusiform shape is quite energy efficient for swimming. Compared to other body shapes, this body shape creates less drag (the opposing force an object generates as it travels through water).
