When it comes to lobsters, the ugly greenish brown ones are standard. Only one out of every 30 million carries a charming genetic mutation that renders its shell a shade of dandelion. When a yellow fellow turned up in a seafood shipment at a Rochester-area Wegmans Monday, employees immediately took note.

Wegmans nobly donated the golden pincher to the Aquarium of Niagara. As S.J. Velasquez of Buffalo.com notes, it’s the second PR boost the grocer’s seafood department has gotten recently—Greenpeace gave the store top marks for improving selection of sustainable seafood in 2009. Whether a grocery store wants the approval of Greenpeace is another story, but it’s probably better than having the organization destroy your modified wheat or vandalize your property.
