Supercrabs: The coming crustacean cataclysm

By Michael J.W. Stickings

Well, this is rather worrying:

It is the dawn of the super crab.

Crabs are bulking up on carbon pollution that pours out of power plants, factories and vehicles and settles in the oceans, turning the tough crustaceans into even more fearsome predators.

That presents a major problem for the Chesapeake Bay, where crabs eat oysters. In a life-isn't-fair twist, the same carbon that crabs absorb to grow bigger stymies the development of oysters.

"Higher levels of carbon in the ocean are causing oysters to grow slower, and their predators — such as blue crabs — to grow faster," Justin Baker Ries, a marine geologist at the University of North Carolina's Aquarium Research Center, said in an recent interview.

Over the next 75 to 100 years, ocean acidification could supersize blue crabs, which may then eat more oysters and other organisms and possibly throw the food chain of the nation's largest estuary out of whack.

Humans are really fucking things up, aren't they?

  • Gee, just when pubic lice are on the verge of extinction, we get this...

    How ironic.

    Revenge of the Crabs, coming to a 3D theater near you!

  • I can relate. My coastal area of Florida has a huge problem with giant blue crabs which live on land and reproduce in the water. On full moon nights in late Summer we can be treated to an immense moving carpet of red and blue -- thousands and thousands and thousands of these stinky things blanketing lawns and roads and crawling into garages and enclosed patios like a scene from some cheap apocalyptic movie directed by Ed Wood.

    The rest of the year they make a mess of your lawn and shrubbery by digging thousands of holes. They can collapse porches and air conditioning units by undermining them.

    For some reason Florida thinks they need to be protected so I have to live with this seasonal horror.

    Needless to say, I laughed myself sick at that poster!
