Jumbo Squid Invading Eastern Pacific

Flotillas of jumbo squid are invading the length of the eastern Pacific Ocean, and the voracious predators may be upsetting ocean ecosystems and threatening fisheries, scientists warn. At their largest, jumbo, or Humboldt, squid (Dosidicus gigas) can extend to six feet (two meters) in length and weigh more than 100 pounds (45 kilograms) each. The squid have earned the nickname "red devils" for their powerful arms and tentacles, razor-sharp beaks, and insatiable appetites.
