@Toad, they lack any porpoise
@Toad, Darn, I thought he was a Vancouver Canuck
@Toad, boom, case dropped.
Dolphinately not a killer... oh the humanatee you did that on porpoise
Actually he's a dolphin, so...
@SWAT the fireman, a cetacean. Not a dolphin.
@CleverBastard, They're not porpoises. They're dolphins. (Right?)
@CleverBastard, dolphins are cetaceans and orcas are the biggest dolphins
@Jdrawer, [as a Marine Science Major] Cetaceans include all whales, which includes a large number of marine mammals. It includes everything from blue whales, beaked whales, orcas, and dolphins. Further down you have odontoceti and mysticeti (toothed and baleen whales). If you want to generalize, the more proper generalization is to called orcas toothed whales, which can also be said for dolphins and porpoises. The easiest and most broad generalization to make is calling them cetaceans, literally a word that stems from the latin for Whale.
@AdMae91, referring to my previous comment, it would be more proper to call porpoises and dolphins the smallest whales, not calling orcas "biggest dolphins". Orcas are some of the largest odontocetes which includes a wide range of marine mammals such as dolphins, porpoises, sperm whales, and even narwhals. They are also further differentiated by their differences in blowhole morphology and use. All of which are characterized as toothed whales.
"Your mum would know...im a sperrrrm whale"
