Oysters are disappearing from coastlines around the world because of overharvesting and disease, researchers said.
An estimated 85 percent of global wild oyster reefs and beds vanished in the past 20 to 130 years, according to a study led by Michael Beck, lead marine scientist at the University of California at Santa Cruz. His team examined oyster reefs in 144 bays across the world, historical records and national catch statistics in a study published in the February issue of the journal BioScience. The condition of oysters was rated as “poor” overall.
ScienceDaily (Feb. 5, 2011) – Things are not always what they seem when it comes to fish — something scientists at the Smithsonian Institution and the Ocean Science Foundation are finding out. Using modern genetic analysis, combined with traditional examination of morphology, the scientists discovered that what were once thought to be three species of blenny in the genus Starksia are actually 10 distinct species.

I thought I’d share the latest post by David Suzuki and Faisal Moola at the David Suzuki Foundation concerning the recent news about birds dropping dead from the sky and mass fish kills, etc.:
Aflockalypse Now: Mass animal die-offs and the ongoing extinction crisis
On New Year’s Eve, 5,000 red-winged blackbirds dropped out of the sky in Beebe, Arkansas. Necropsies revealed no evidence of poisoning but did indicate the birds had suffered massive internal trauma. Days later, fisherman observed schools of fish floating belly up on Chesapeake Bay. In England, tens of thousands of dead crabs washed up on local beaches, and reports come in almost daily of penguins, turtles, and even dolphins dying unexpectedly in the wild. Are these events signs of the “aflockalypse”, as the media have dubbed the recent die-offs? The answer is yes. And no. Read on >>
Discovered by an international trio of scientists, the lobster, Dinochelus ausubeli, lives in the deep ocean water near the Phillipines.
The new lobster has movable, well-developed eyestalks and an inverted T-plate in front of its mouth.
But its most striking feature is a mighty claw with a short, bulbous palm and extremely long, spiny fingers for capturing prey.
Dinochelus is derived from the Greek words dino, meaning terrible and fearful, and chelus, meaning claw.
All told, the Census of Marine Life sponsored 540 expeditions over 10 years, carried out by 2,700 researchers from more than 80 countries. It was, Ausubel says, the biggest project in the history of marine biology.
This is one of the most important reasons why we need to fight harder to stop climate change. The loss of these precious ecosystems is a tragedy.
The Wildlife Conservation Society has released initial field observations that indicate that a dramatic rise in the surface temperature in Indonesian waters has resulted in a large-scale bleaching event that has devastated coral populations.
WCS’s Indonesia Program “Rapid Response Unit” of marine biologists was dispatched to investigate coral bleaching reported in May in Aceh — a province of Indonesia located on the northern tip of the island of Sumatra. The initial survey carried out by the team revealed that over 60 percent of corals were bleached. Continue reading →
So I mosey on over to the Shark Week homepage and the first thing I see is the word ATTACK. Sigh. I guess to draw people into watching shark week they have to plaster the word ATTACK everywhere to get people’s attention. The good news is, they are making an effort toward shark conservation on the website: http://dsc.discovery.com/sharks/shark-facts-tab-04.html. There’s lots of information on sharks and shark conservation there. In between reading, you can go watch “Into the Shark Bite!” and “Shark Attack Survival Guide!” and “Shark Bite Beach!” Continue reading →
75 tons of blue shark laid out on the dock in the Japanese fishing port of Kesen-numa City, July 6th, 2010. The day before, 44 tons of blue shark, ten tons of salmon shark and three tons of short fin mako were seen here… this happens 6 days a week, all year long… Continue reading →
If you haven’t already, check out the TEDx Oil Spill conference. It was held/streamed live on June 28 from Washington DC and featured an impressive number of speakers including Sylvia Earle, Carl Safina, Philippe Cousteau, David Gallo (Woods Hole), Andrew Sharpless (Oceana) and many others on the oil spill, the future of energy, and what this event means for our blue planet. The oil spill is a call to action for all oceans. Topics include mitigation of the spill and the impending cleanup efforts; energy alternatives; policy and economics; as well as new technology that can help us build a self-reliant culture.
…unless the cause is toxic. I came across this image on Facebook and it really hit close to home. It was posted by one of my BFF’s from high school (hi Michelle!). A BFF whom I’d spent a week on this very coast during Spring Break ’84 in Panama City! I wish I could share fond memories from that trip, but all I remember is eating the worm. And driving Sabrina’s Oldsmobile because she was too sunburned…. Continue reading →
I’m an ecologist, mostly a coral reef ecologist. I started out in Chesapeake Bay and went diving in the winter and became a tropical ecologist overnight. And it was really a lot of fun for about 10 years. I mean, somebody pays you to go around and travel and look at some of the most beautiful places on the planet. And that was what I did.

Oceana Releases New Report about Impacts of Oil on Sea Turtles and Threats to Populations
June 10, 2010
Contact: Dustin Cranor (firstname.lastname@example.org)
Oceana, the world’s largest international ocean conservation organization, released a new report today that finds the Deepwater Horizon oil spill extremely dangerous for sea turtles inhabiting the Gulf of Mexico. Specifically, sea turtles can become coated in oil or inhale volatile chemicals when they surface to breathe, swallow oil or contaminated prey, and swim through oil or come in contact with it on nesting beaches.

(CNN) — Since I began exploring the ocean as a marine scientist 50 years ago, more has been learned about the ocean than during all preceding history.
At the same time, more has been lost.
Two weeks ago I testified before U.S. Congress on the ecological impact of the oil spill in the Gulf of Mexico. I did so with perspective gained while sloshing around oiled beaches and marshes among dead and dying animals, diving under sheets of oily water and for years — as a founder and executive of engineering companies — of working with those in the oil industry responsible for developing and operating sophisticated equipment in the sea.
