I'm not sure... but my guess is that the california spiny lobster doesn't extend down to the Sea of Cortez. Maybe there's a different kind of lobster? I'll let ya know ((80 degree water -> I swear I'm not rubbing it in, well, umm... honest, kinda sorta))
I don't know if they are the exact same species down there but I nabbed three nice bugs down in Puerto Vallarta last March and they sure taste like so-cal bugs!!! I was diving with a friend who owns a dive shop there and he took us to a restaurant where they took our bugs and chopped them in half lengthwise and broiled them along with huge coconut prawns and some fresh filets....that was the best dinner!!! So they do have some kind of bugs down pretty far south!!!
