One lucky lobster got a stay of execution this week after a popular Facebook post about the blue-tinged crustacean led to owner Cape Quality Seafood promising not to sell it.

Amy Nell was visiting the Dartmouth Street seafood market with her six-year-old daughter Bridget Stechschulte on July 28 when Stechschulte noticed an unusual blue lobster for sale.

“She’s very interested in animals,” noted Nell about her daughter, who does not eat lobster.

Nell said that the girl working at the counter was nice enough to pull the lobster out of the tank so everyone could have a better look.

“We all played with him,” Nell said, adding, “My son suggested that we buy it and save it, but I did not like the idea of keeping it in our bathtub.”

Nell’s mom Carolyn said that she posted a few of her daughter’s photos of the creature — which she called ‘Big Blue’ — to Facebook, and “instantly, like within a minute, people were commenting.”

The post caused a bit of a stir, with some commenters in favor of saving the lobster, and others in favor of eating it. 

“Many had no opinions but of those who did, 15 say save him, seven say eat him,” Carolyn noted.

“There were some funny [comments] on there,” she added. “One of them, of course, is ‘Blue Lobsters Matter.’”

Cape Quality Seafood Market manager Josh Benevides said that the lobster, which is actually a female, will not be sold.

“It’s not really a true blue lobster,” he noted. “[But] it’s definitely not the same color as a regular one.”

According to Benevides, the lobster — which has yet to be named — comes from local waters, probably off Nantucket, and weighs about six or seven pounds. This means it could be around 50 years old.

“Now with all the buzz about it, we’re keeping it,” he said, going on to note that this isn’t the first lobster that Cape Quality has decided to save. 

“Some of them we donated, like we gave [a rare yellow spotted] one to the New England Aquarium, and I gave one to the Buttonwood Zoo,” he stated.

As for this particular lobster, Benevides said, they might donate her — but for now at least, “She’s kind of just hanging out.”

“She’s pretty happy, I think, because she’s staying,” he added. “I’m going to feed her some scallops and see how she does.”
