The Associated Press is reporting that thousands of jumbo flying squid, also known as Humboldt squid or, more alarmingly, "red devils," are showing up in the shallow waters off the coast of San Diego, taking a number of divers by surprise.
Jumbo squid are usually found in much deeper, tropical waters off the coasts of Mexico and Central America. It isn't clear yet why they've come to California, but this isn't the first time they've taken the trip. Similar incidents were reported in 2002 and 2005. In fact, researchers believe they may have established a population in nearby, deeper waters, possibly due to a change in the number of their prey or predators. Similarly, the squid were likely drawn into the shallower areas as they followed their food.
The swarm presents a rare opportunity for divers to see these amazing creatures up close. However, the "red devils" are known for attacking humans- San Diego divers report being grabbed and knocked around. One even captured the near-theft of his camera light on video.
Many media outlets are referring to the squid's arrival as an "invasion." However, as at least one astute commenter pointed out, just who is invading whose territory isn't exactly clear.
