If you didn't know, there are multiple types of orcas in existence, each with different appearance and behavior. Here, I will explain the different orca types.
Type A
Type A orcas are the largest of the four types. This orca type is the one you would generally see if you looked up orcas on google. These are the orcas that pop into my head when I think about orcas. The type A orcas get up to 10 meters long, making them the largest of the four orca groups. They like to eat larger prey, like minke whales, which they follow up to antarctic waters. These orcas also like sea lions, often beaching themselves on purpose to feed on baby sea lions
A type A killer whale
Type B
Type B orcas often have yellow hues/a yellow cast because of diatoms. Type B orcas also like to hunt mammals like seals. They are well known for their hunting strategy, which involves making waves to knock seals off ice flows. I personally think that this orca strategy is genius, and I also wonder how long it took them to make it
Type C
Also called Ross Sea killer whales, can grow up to 6 meters long. These killer whales are paler than other killer whales and have the same yellow cast as the Type B orcas. They are often found in the ross sea (duh), which is a bay in Antarctica. They are believed to eat Antarctic Toothfish. These are my personal favorite orca type because of the unique color.
Type D
Type D killer whales, also called subantarctic killer whales, are the rarest type of killer whales. We know little about these orcas, but we do know that they eat Patagonian Toothfish. They have short dorsal fins, rounded faces, and extremely small eye patches that make the eye patches look like the eyes themselves.
