After more than 40 years on the job, 10th generation lobsterman Alex Todd of Chebeague Island, Maine recently pulled in a crustacean even he had never seen: a translucent lobster.
He's quoted in the Guardian as saying, “I was definitely surprised," and "It was like it was clear but with white under the clearness and a blue tint, but you couldn’t see organs or anything under the shell, it wasn’t to that level.”
The Maine Coast Fishermen's Association shared a little info about the lobster's unusual pearly look, on their Facebook page:
A normal lobster gets its color by mixing yellow, blue, and red protein pigments. Through different genetic mutations you can get a blue, yellow, or red (uncooked) lobster. You can also get strange mixtures of those colors as well.
This lobster probably has a genetic condition called Leucism which isn't a total loss of pigment (which would make it an albino) but instead a partial loss. This is why you can still see some hints of blue on the shell and color on the eyes.
