Q: Is an orca a dolphin or a whale?
A: Orcas, also known as killer whales, are technically dolphins. They belong to the oceanic dolphin family (Delphinidae), which makes them the largest member of the dolphin family.
Q: Why are they called “killer whales” then?
A: The name “killer whale” comes from early sailors who called them “whale killers” after seeing them hunt large whales. Over time, the name flipped to “killer whale,” but it’s a bit misleading—these intelligent predators are actually dolphins.
Q: Are dolphins and whales the same thing?
A: Sort of! Both dolphins and whales are cetaceans—a group of marine mammals that includes whales, dolphins, and porpoises. Dolphins are a subgroup within that larger cetacean family.
Q: So, how do scientists classify orcas?
A:
- Order: Cetacea
- Family: Delphinidae (oceanic dolphins)
- Genus/species: Orcinus orca
Q: Do orcas behave more like dolphins or whales?
A: Orcas share traits with both—like echolocation and social behavior seen in dolphins, and the ability to take down large prey like whales. They live in tight-knit family pods and display advanced hunting techniques.
In short: Orcas are dolphins by classification, but whale-like in size and power.
