Orcas and Humans

Orcas are efficient hunters; however, they hardly ever attack humans. In fact, many orcas have been trained to perform at aquatic theme parks. Their intelligence, receptive nature, and appearance have made them suitable creatures for performing in theme parks.

Orcas are among the world's most feared predators. These marine creatures belong to the Delphinidae family, which comprises different kinds of oceanic dolphins. In fact, the orca is the biggest member of this group. Some of the others include the Pygmy Killer Whale, False Killer Whale, and the Melon-headed Whale.

Killer whales can survive in the cold polar regions of Antarctica and the Arctic Circle, as well as the warm waters of the equatorial regions. Orcas are not just fierce hunters, but also intelligent creatures. This characteristic shows in the way they use creativity while hunting.

Reasons Why Orcas Are Called Killer Whales

The name 'killer whale' is actually a misnomer, because killer whales do not belong to the group called whales. In fact, they are dolphins. So, why are these dolphins called killer whales?

Orcas Named as Killer Whales by Spanish Sailors

The orca's bold black-and-white markings and white eye patch make it one of the most recognizable animals in the ocean.

The name 'killer whale' was given to orcas by Spanish sailors. These sailors, who traveled to distant locations by sea, had often witnessed the hunting skills of orcas. The Spanish sailors named them Matador de Ballenas. This term is literally translated to English as 'killer of whales'.

Somehow, the order of the words 'killer' and 'whale' was not changed. As a result, the name 'killer whale', instead of 'whale killer', got associated with orcas. It is not clearly understood whether it was an error in translation or whether the name was simply accepted as it is. The Spanish sailors called them killer whales because these creatures preyed on different kinds of whales. They didn't even spare the bigger whale species.

How large can an orca pod be?

Orcas Are Efficient Hunters

Killer whales are known to prey on different kinds of sea creatures, regardless of their size and type. Carousel fishing, echolocation, and hunting in pods are some of the techniques used by killer whales for hunting.

In this technique, killer whales from a pod surround a school of fish. After doing so, the orcas spew bubbles on the fish. They may also hit the prey with their tail. As a result, the prey gets distracted and becomes vulnerable to an attack.

Echolocation

This is one of the most efficient techniques used by killer whales to find their prey. In the echolocation technique, orcas produce sonar clicks that bounce back after striking an object. This way, the location of the prey is easily found.

Orcas hunt in groups of 30-40 called pods. The number of orcas in a pod can be up to 100. The technique most commonly used by killer whales to hunt whales is chasing.

Orcas in Our World

Until the 1960s, very little was known about killer whales. These creatures are great hunters; however, they do not show the same aggression toward humans that they display while hunting. Today, the growing appreciation of killer whales has led to opposition against keeping them captive in aquaria. Movies like Free Willy have helped create awareness about killer whales. In all, orcas are interesting creatures, and one should not equate the fierceness in their name with their behavior toward humans.
