Someone caught a half red one in Maine.

Someone caught a lobster half red and half blue in Maine.

Lobster actually has many colors, and some are naturally red (not cooked), depending on the relationship between astaxanthin and other proteins, which simply bind the pigments so that they do not appear. (Of course, the protein denatures after boiling, so it turns red.)
Then the color-matched lobster belongs to the "chimera", which is a problem when embryonic cells divide. Because the germ cells do not mix well when they combine (fog) and fail to separate well at the stage of determining symmetrical development, they are half as long as each other, mostly male and female inlays. This is also true of insects. There’s probably one in millions.

It is said that the New England Aquarium in Boston can see some unusual inlays (live, figs. 3 and 4).

In addition, people have worked hard to grow up like this, so don’t think about how delicious they are (can lobster be delicious????????????????????????????????????????????????
