More than 6,000 octopuses gathered off the coast of California in unusual congregation

The largest congregation of deep-sea octopuses ever discovered on Earth has been located off the coast of California in an unusual "octopus garden". More than 6,000 octopuses are huddled around an extinct underwater volcano, almost two miles below the surface. KTVU's Alex Savidge and Heather Holmes speak with Chad King, research ecologist at Monterey Bay National Marine Sanctuary about what they octopuses are doing there.
