Orcas live in the icy waters around Alaska and other areas around the Arctic Circle. The waters are very cold and are filled with chunks of ice and meager vegetation.
Orcas can be found in the cooler water regions. Orcas can be reliably seen on tours around Vancouver Island, off Antarctica, Norway, and Iceland, and occasionally in many other areas. However, Orcas can be found in all oceans and most seas.
Orcas have often been seen killing sharks by biting and eating them. The tactic you describe has been seen used by dolphins, but not Orca.
A pod can be defined as those orcas that are usually seen travelling together, so yes the male and female stay together.
The best place to see wild transient or resident Orcas - Transient Versus Resident is Off the coastal waters of Washington.
