Orca meets Great White

Stockvault.net - Chris Adzima
What will happen? Although most of the time they will go their own way, especially when comparable in size, there have been cases of orca preying on great whites. The most prevalent example is "The Whale That Ate Jaws" by National Geographic.

How do they do it? Well, according to the scientists of the National Geographic team, the orca charges in and tackles the shark upside down, inducing tonic immobility. That apparently, anaesthetizes the shark, and allows the killer whale to chomp down on a defenceless apex predator. Looks like they weren't equals after all.

What's even more amazing (if you managed to watch the entire video) is how all other sharks in the area, during seal hunting season, escaped elsewhere as they detect the semiochemical of their fallen comrade. Intelligence makes the difference in the end.
