Quick: What color are lobsters? If you’re a fan of the seafood chain, you probably said red.

But, unlike the seafood chain, real-life lobsters come in a variety of colors. One of the most rare of those colors is a near-sapphire blue.

Wayne Nickerson, a veteran commercial lobsterman, just ensnared an ultra-rare blue lobster while off the coast of Cape Cod on Monday.

Oceanographers estimate that only one in every 2 million lobsters is blue—although they can also come in yellow or green. The rare tint is caused by a genetic mutation that causes the lobster’s body to produce an excess of a certain protein.

Nickerson separated the lobster of a different color away from the rest of his catch. He is hoping to give the two-pound lobster, nicknamed Bleu, to a local aquarium so people will “be able to see him,” Jan Nickerson, his wife, told ABC News.

This is the second blue lobster than Nickerson has caught in his 35-year career.

Most lobsters caught in the North Atlantic are a green-brown color when caught and only turn orange or red when cooked.

Some oceanographers estimate that the yellow lobster is even more rare than the blue, with only one in every 30 million lobsters.

And then there’s the bright white “albino” lobster that is estimated only to be found in one out of every 100 million lobsters.
