12
miles of dead squid wash ashore

APTOS,
Calif. (KPIX/CNN) - Scientists are investigating why several hundred
dead squid have washed ashore along California beaches.
The
beaches of Santa Cruz County are littered with carcasses of thousands
of Humboldt squid. They've stranded themselves from Aptos to
Watsonville, a span of 12 miles.
"You
just see them essentially killing themselves and it's just really
weird to see," said Hannah Rosen with Hopkins Marine Station.
It
happened during high tide. Some people actually tried to put them
back in the water, but Rosen says the deepwater creatures swam right
back to shore.
"They
don't see the shore very often, so it might just be that they don't
understand what's going on around them, and they're just trying to
get away and don't realize that if they swim towards the shore,
they're going to run out of water eventually," she said.
They're
juveniles, both male and female, about a foot and a half long,
weighing roughly three pounds each. They had full stomachs, having
feasted on smaller market squid. A few had also cannibalized each
other, which is normal.
Researchers
have no idea why this is happening, but they think it's because the
squid have eaten toxic algae.
"It's
possible that the squid are ingesting either these neurotoxins or
they're getting it through their food, and that could be causing them
to be disoriented and swim onto the beach," said Rosen.
Humboldt
squid have not been seen in the Monterey Bay area for a few years.
Scientists
believe El Nino weather patterns may have drawn them to the cooler
waters of northern California.
This
is the third stranding in six weeks.
"It's
really an exploratory time for us, so we're learning more about what
causes these strandings, and whether or not we should be worried
about them or if it's just a natural part of the squid cycle,"
said Rosen.
