How do orcas hunt?
How do orcas hunt? Herding fish before stunning them with tail strikes is one of many ways in which these predators hunt their prey. As highly intelligent predators, orcas also work together in coordinated attacks to create waves that can knock prey off floating ice into the water.
Why do killer whales hunt in groups?
When it comes to finding food killer whales can often be found hunting together as a team creating strategies to capture their prey. They work together to isolate, tire out and immobilize their prey and then share their food with other family or pod members.

Do orcas hunt in packs?
Orcas hunt in deadly pods, family groups of up to 40 individuals. There appear to be both resident and transient pod populations of orcas. These different groups may prey on different animals and use different techniques to catch them.
How many orcas are in a pod?
Pods usually consist of 5 – 30 whales, although some pods may combine to form a group of 100 or more. Orcas establish social hierarchies, and pods are led by non-reproductive older females, who often teach hunting skills and help feed younger relatives.

Whales generally stay in pods of two to three (female, calf, and escort), but can be seen in larger groups in breeding areas when males congregate to compete for females—called a “competition pod.”
What happens when orca pods meet?
When meeting killer whales from other family pods, they made contact with each other, swam in synchrony and rubbed flippers much more often, the researchers found. Sexual activity also increased, suggesting that these big aggregations provide a chance to assess potential breeding partners.
Why do orcas live in pods?
The largest member of the dolphin family, orcas are highly intelligent and social animals, spending their lives in groups or pods where they hunt together and share responsibility for raising young and taking care of the sick or injured.
Do orcas drown their prey?
When the orcas do catch a grey whale, they will kill it by drowning, holding the whale’s blowhole underwater until it expires. At this point, the key is timing. A whale carcass will sink. In water too deep, it will sink beyond the orcas’ reach.
Are orca pods matriarchal?
Because orca (also known as killer whale) societies are matriarchal, it’s likely that these older females carry with them crucial knowledge about food resources that can mean life or death for their kin.
Why are orcas so violent?
In captivity, when orcas attack, it’s usually believed to be because they feel threatened or are under emotional distress. Some researchers believe this behavior may stem from the idea that they feel isolated, since they are usually with their pod, or family, in the wild.

The whales seem to understand people, and are eager to cooperate and create bonds.

Many experts think these attacks are not malicious, rather a case of play getting out of hand.
Has an orca ever attacked a human in the wild?
Orca attacks on humans
There is no record of an orca ever killing a human in the wild. This is because humans are not part of their natural diet. Occasionally, an orca may mistake a human for something they do eat, such as a seal.
