Seems like three weeks or so ago I heard that an Orca had beached itself somewhere on Oahu. They couldn't get it back in the water so it was put down. Would be interesting to know what the cause of the beaching. I've never came across anything saying Orcas were more dangerous than sharks. In fact, everything I've ever read would indicate that Orcas are the most willing of all Cetaceans to interact with humans.
