If you want quicker updates, in 140-character bites, you'll find me on Twitter(@aquaken). The aquarium tweets @MontereyAq, and if you're a fan of sustainable seafood, try following @SeafoodWatch.
-- Singing Blues: California researchers have noted that blue whales are singing their songs at a lower octave than they did in the 1960s, and they speculate their voices may have dropped because they're feeling more comfortable now that they're not being hunted by whalers. The Los Angeles Times blogs about it nicely.
-- Demon Macaws in Klingon Cloaks: For sheer elegance in a turn of phrase, check out this item from the Deep Sea News blog about Humboldt squid proliferating along the California coast.
-- 'Magical' Marine Megabacteria?: Off the coast of Chile, scientists are studying marine megabacteria that may become a source of hydrogen for clean-energy vehicles, or even to kill cancer cells in the blood.
-- Oscar Nominee: Finally, The Cove -- the film that brought to light the horrors of a Japanese drive fishery that slaughters dolphins in secrecy -- was nominated for an Academy Award as Best Documentary Feature.
