The Humboldt Squid has not been listed by either the IUCN Red List or the CITES, not because they don't need protection, or they aren't endangered. But due to the "dearth" of knowledge, research and study concerning their size, reproduction numbers, and their population numbers now. They are heavily fished off the coast of Mexico, and currently seem to be moving northward even as far as Alaska. Some ecologists suspect this may be due in part to over fishing their predatory fish, while other researchers feel it is due to the change in ocean temps. Either way, many people feel the move up the coast through more populated waters has created fear of the Jumbo Squid and it's little understood lifestyle. This fear could cause organizations depending on donations, to with hold their support of the Humboldt "Jumbo" Squid for full protected status. This is apparently a problem faced often due to lack of public education, and the public's image of the animal, earned or otherwise. For more details please see site listed below.
