While all three types share at least part of their habitats, they are not known to interbreed with each other. Killer whales in Alaska.

Although residents, transients, and offshore orcas are all members of the same species, they have not been observed to interbreed.
How strong is an orcas bite?
For animals living today, the Orca is the largest animal that uses it's teeth to kill and dissect prey, and has the strongest unconformed bite force of nearly 20,000 pounds per square inch.
Do killer whales eat pilot whales?
Orcas compete for food with long-finned pilot whales and are potentially their predators. Evidence from orca stomachs shows they do occasionally eat pilot whales. But pilot whales can mob and chase orcas away, the only cetaceans seen defending themselves from the apex predator in this way.
What is a Type B Orca?
Type A killer whales are the largest type of killer whale, known to reach up to nearly 10m in length. Their size comes from their diet of large prey, often minke whales which they follow through the Antarctic waters and further north into other regions of the Southern Hemisphere.
Do orcas protect humans from sharks?
