Thanks! Cetacea order are all whales, but it’s (the dolphin eg Orca) not considered a whale proper (like a blue whale, or a sperm whale…) they differ slightly. So Marine Biologists generally keep the distinction, since the Orca is mistakenly called the Killer Whale (a derivation of Whale Killer, which is more accurate, though perpetuates a negative space of thought for many humans about them). He should have reiterated the differences and that they are part of the order.

From Brittanica:
Whale - any of the larger species of aquatic mammals belonging to the order Cetacea. The term whale can be used in reference to any cetacean, including porpoises and dolphins, but in general it is applied to those more than 3 metres (10 feet) long.

I’d say an Orca would qualify by that definition, since they are usually 20-27 feet long. Orcas kill many species, and will pretty much eat anything they can catch and swallow, unlike most dolphins and porpoises. There is one video on YT of a seal running from orcas and he jumps onto a fishing boat to save himself. They are well known for killing seals, and sometimes even slide up onto the beach to do so. I think they qualify as whales.

I think he may have explained them further, and may in another episode, but it is probably on the cutting room floor.
