Giant Squid Kill Fishermen, courtesy of Weekly World News, "The World's Only Reliable News."

Marine biologists rushed to the scene hoping to catch at least one of
the squid. Dr. Luis Santiago of the Universidad Autónoma Baja
California Sur explained, “We captured one of the attackers. She is
female and we believe most of the pack to be female because of their
size. We also believe they coordinated the attack by using pigment cells
to communicate, which is very typical in a situation like this. I’m
afraid we may be seeing more of these attacks in the coming years, and
possibly forever."

Beaches in the area are closed indefinitely, and fishing boats are
banned from heading out to sea until authorities can determine a
squid-free safety zone.

Yes. It's a joke. Nevertheless, only one of these "facts" is false:

Many legends surround the giant squid because of their size and their
gang mentality. They have eight arms and two tentacles, all covered in
suction cups lined with small teeth. They also have three hearts and
eyes the size of soccer balls. They hunt in groups of at least 1,000.

(It's the last one.)
