Sea killer whales ( Orcinus orca ) are popularly known as killer whales. These animals belong to the Delphinidae family, so they are dolphins despite being called whales. In fact, orca whales are the largest dolphins in existence. Killer whales do not usually attack people. However, they are capable of killing large species such as whales or sea lions. To hunt, they use their huge teeth that can grow up to four inches long.
These animals stand out for their long dorsal fin and their black and white color. Furthermore, orcas are considered the largest species in the dolphin family. They weigh around 5,400 kilograms and can grow up to 9.7 meters when fully grown. That is, the same size as a school bus. The largest killer whale ever recorded, according to Sea World, was 9.8 meters long.
On the other hand, orcas are highly distributed mammals, since they inhabit the oceans and seas that surround most coastal countries. They adapt to practically any climate, so it is possible to find them both in the warm waters of the equator and in the icy waters of the North Pole regions.
