What is an orca?

An orca, also known as a killer whale, is a highly intelligent and social marine mammal that belongs to the dolphin family. Orcas are found in every ocean in the world and are known for their striking black and white markings.
What do orcas eat?

Orcas are apex predators and have a diverse diet that includes fish, squid, octopus, seals, sea lions, and even other whales. Their hunting techniques vary depending on their prey, but they are known to work together in groups to catch larger animals.
How big do orcas get?

Orcas can grow up to 30 feet long and weigh up to 10 tons, making them the largest member of the dolphin family. Male orcas are typically larger than females and have longer dorsal fins.
Where do orcas live?

Orcas are found in every ocean in the world, but they prefer cooler waters and are most commonly found in the North Pacific and Arctic oceans. They are also found in the North Atlantic, Southern Ocean, and Antarctic waters.
Are orcas dangerous to humans?

While orcas are powerful predators, there have been very few recorded incidents of orcas attacking humans in the wild. In fact, there are many cases of orcas protecting humans from other predators in the water.
Are orcas endangered?

Orcas are not currently considered endangered, but some populations, such as the Southern Resident orcas in the Pacific Northwest, are listed as endangered due to declining populations and threats from pollution, climate change, and overfishing of their food sources.
How do orcas communicate?

Orcas have a complex communication system that includes a variety of vocalizations such as whistles, clicks, and pulsed calls. They also use body language and touch to communicate with each other. Scientists believe that orcas have their own unique dialects and can recognize the calls of other orcas in their pod.
How long do orcas live?

Orcas have a long lifespan, with some individuals living up to 90 years in the wild. Females typically live longer than males, and their lifespan can be affected by factors such as food availability, pollution, and disease.
Do orcas migrate?

Some populations of orcas are known to migrate seasonally in search of food or to breed. For example, the transient orcas found along the West Coast of North America travel up and down the coast in search of prey, while the resident orcas in the Pacific Northwest have a more limited range and stay close to their preferred hunting grounds.
How do orcas hunt?

Orcas use a variety of hunting techniques depending on their prey, but they are known for their ability to work together in coordinated groups to catch larger animals. They may use a technique called "carousel feeding" where they swim in a circle around a school of fish, creating a wave that washes the fish onto the shore. They may also use their powerful tails to stun or knock their prey unconscious.
Can orcas be kept in captivity?

Yes, orcas have been kept in captivity for public display and entertainment, but there is growing concern about the welfare of captive orcas. Many countries have banned the practice of keeping orcas in captivity, and there is a movement to retire and release captive orcas into sanctuaries where they can live in more natural environments.
How do orcas sleep?

Orcas have to be conscious to breathe since they are mammals, and they sleep with one hemisphere of their brain at a time. This means that they can rest while still being aware of their surroundings and maintaining bodily functions. They will typically swim slowly and close to the surface while sleeping to make sure that they can come up for air.
