While squad are not usual in California waters -- market squid fishermen hauled in record numbers as ocean conditions for the third-straight year – this particular species is rare.
Called Humboldt squid, the species are most commonly found in Baja's Sea of Cortez. However, the warmer El Nino currents this year may have brought them northward in large numbers.
"When they re-colonize an area, the vanguard usually goes through this kind of stranding behavior," Professor William Gilly, who is on the faculty at Stanford University's Hopkins Marine Station and has studied the Humboldt squid for more than two decades, told the San Jose Mercury News.
Gilly said the dark red squid, 2 to 3 feet long with enormous eyes, have been observed in the Monterey Bay area over the last three weeks.
It was the second major die-off of the squid this year. In October, about 100 squid beached themselves in the Pacific Grove area.
