How do orcas manage to stay together for their entire lifetime? What precautions do they take to keep from getting separated?

I understand that they have certain frequencies that they use to communicate. what happens if they get out of range of each other? Do they have a common route or meeting place where they can try to join back up? Or do they then have to try to survive on their own or join another pod?
Do they all have to synch their sleeping schedules? What happens if one wants to take a nap but others want to stay on the move?

Each pod has its own unique sounds, which can be heard from a very great distance. Calves are protected by the entire pod and stay close to their mothers most of the time. I can attest to cases where I’ve seen calves gathered in the center of a fjord with a "babysitter" from the pod—there is a theory that she is the one who will become the future leader of the group—while the adults head out to hunt. From this, we can learn about the Orca's way of protecting individuals within the pod, ensuring a direct connection between everyone and maintaining constant knowledge of where each member is located. This is based on observations, so I cannot state it as a definitive fact yet.

love this question. from what i understand about orca pods, they are built around the oldest mom/grandma in the group, and her kids and grandkids literally never leave her. Males stay with their mothers their whole lives which is wild when you think about it.
The communication range thing is huge too. They can hear each other from miles away, and on top of that each pod has its own distinct calls that only they use. So even if one gets separated they can basically just call out in their family language and find each other.
and for sleeping, they do this thing called logging where the whole group just kind of slowly drifts at the surface together while half their brain rests. So they're never fully knocked out, which means they don't really have the problem of one wanting to sleep while others don't.

They do get separated and then usually regroup, especially Bigg’s transients, but sometimes youngsters have gotten lost, like Luna in 2001 and Springer in 2002, both about 2 years old. They must have strict rules about stay in contact at all times.

From what I read online, Orcas can hear each other for miles, so that out of range thing is a little more difficult than not. They will also have a roster to their pod of places they like to go, and for non resident pods it’ll be the routes they like to take. So my hypothesis would be that if an adult whale gets lost then they could probably draw on that memory to regroup with the others.
Orcas also do that thing where they can rest hald of their brain, and the other half remains -awake- to keep them breathing and moving.
