The jelly fish you are describing sound like what we call "cabbage heads" here in the northern Gulf of Mexico. Some of the true Cajuns eat them in various ways. One is pickling them. Never tried it and never will.
Those other retards must have Stuart jammed up because I have not heard from him regarding prices. Will give you a shout if and when he can break loose from trying to babysit the "tards"!!!!
Incredible biomass there!!!! Obviously a marine sanctuary, but is that indicative of the northern reaches of the Sea of Cortes??? Have fished Cabo and Lapaz a number of times but strickly for pelagics
