Poor Bubba, he didn't even have a chance:

PITTSBURGH - He dodged lobster pots for decades, endured a trip from the coast
of Massachusetts to Pittsburgh and survived about a week in a fish market. But a
trip to the zoo proved to be too much for a 22-pound lobster named
Bubba.

The leviathan of a lobster died Wednesday afternoon at the Pittsburgh Zoo & PPG
Aquarium about a day after he was moved from Wholey's Market, said zoo
spokeswoman Rachel Capp and Bob Wholey, owner of the fish market.
