orca
This term is used interchangeably with killer whale, though orca is often preferred in scientific and conservation contexts to avoid the aggressive connotation of the word killer. It describes a highly social, intelligent apex predator known for complex hunting strategies and distinct regional dialects.
In biological classification, the orca is the largest member of the Delphinidae family. While the name suggests a whale, it is technically a dolphin, a distinction that is important in zoological discussions.
