I guess this barroom argument can be put to rest.
Info summarized from wikipedia.
Orcas: between 6 and 8 meters long, weighing in excess of 6 tons (male); between 3 and 5 meters long, weighing between 3 and 4 tons.
Great white sharks: between 4 and 6 meters long, weighing between 0.75 and 1.25 tons.
The orcas have a decent weight advantage if not a real length advantage. But we’re talking about a god damned great white shark here, not some idiot school of herring.
My favorite part of the video is that the orcas just rip the shark’s liver out and let the rest sink. Like a giant, “Fuck you, enormous predatory fish! Mammals for life!”
