Orcas are known to be smart and ruthless hunters. They've been observed hunting a variety of prey, with some species, such as whales, larger than themselves. They use a wide range of strategies to hunt and kill prey, but now, in the Gulf of California, researchers have observed one that hasn't been described before.
Cool argument, however i have represented you as the southern hemisphere ross sea orca (with diatoms) and myself as the Type 2 Eastern North Atlantic orca
