Good episode, but some minor comments/complaints:
One, I used to scuba dive in Southern California. Sadly, there are no abalone left, unlike the situation Mike describes. Growing up in the 50s, everyone smoked, and everyone used abalone shells as ash trays. Ha!
Two, Mike's comments that orcas love to eat human beings, and that "they should all be destroyed" are pretty awful. Orcas are beautiful animals, and they should be loved, not destroyed.
Three, that ain't no orca in the episode -- it's a pilot whale, even more harmless than an orca.
Four, I still love Sea Hunt.
