  • A male orca can be nearly 33 feet (10 meters) in length and weigh around 22,000 pounds (10,000kg).
  • Orcas are highly intelligent and able to coordinate hunting tactics.
  • Female orcas are thought to live to 80 years of age or more.

What are killer whales afraid of?

Selbmann says that in the majority of the interactions documented around Iceland, killer whales seem to avoid pilot whales. Occasionally things will get heated and the pilot whales will chase the killer whales at high speeds, with both species porpoising out of the water.

Why do killer whales have two names?

Orcas were given the name ‘killer whale’ by ancient sailors’ observations of groups of orcas hunting and preying on larger whale species. They called orcas asesina ballenas, or ‘whale killer’ – a term that was eventually flipped around to the easier ‘killer whale’.

What is unique about killer whales?

Orcas have a form of culture Scientists have proven that each pod (family) has its own unique dialect and that learned behaviours are passed from one pod generation to the other – a unique feature that is currently known to exist with one other species; humans.

Why do killer whales sleep with one eye open?

Because killer whales are physiologically similar to these species, it’s thought that they sleep in the same way. While half of the killer whale’s brain catches up on sleep, the other half controls the breathing. What’s more, one eye remains open (on the “awake” side of the brain”) while the other stays closed.

What makes killer whales unique?

They’re immediately recognizable by their distinctive black-and-white coloring. Smart and social, orcas make a wide variety of communicative sounds, and each pod has distinctive noises that its members will recognize even at a distance.

Do orcas have eyes?

To avoid drowning during sleep, it is crucial that marine mammals retain control of their blowhole. The blowhole is a flap of skin that is thought to open and close under the voluntary control of the animal.

What is a group of orcas called?

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. Resident pods tend to prefer fish, while transient pods target marine mammals.

How smart are killer whales?

Neuroscientist Lori Marino and a team of researchers explored the brain of a dead killer whale with an MRI and found an astounding potential for intelligence. Killer whales, or orcas, have the second-biggest brains among all ocean mammals, weighing as much as 15 pounds.
