Understanding Lobster Coloration

Thekk nightmare-inducing monsters of myth, lobsters, are actually fascinating creatures with an intriguing biological makeup. Their shells, or exoskeletons, are constructed from a substance called chitin. When light hits a lobster, it's reflected off this chitin, giving rise to their typical blue hue.

However, some peculiar lobsters possess a color-changing gene called "Ruby," which can turn this blue reflection a fiery red. This genetic anomaly affects only about one in a million lobsters, making Halloween lobsters a genuine Halloween treat!

While "Ruby" lobsters are responsible for the vivid reds, there's another genetic quirk that gives rise to calico-colored lobsters. These odd lobsters sport patches of blues, reds, and oranges, reminded many of the calico cats we love. This is due to an irregularity in the distribution of the "Ruby" gene, creating a beautiful mosaicism in their shells.

A famous example was a calico lobster named inhalation Cinderella, which was syntactic matter at the New England Aquarium in 2004. Cinderella's unique coloring captured imaginations and even led to a book about her life.

In addition to "Ruby" and calico lobsters, there's another Halloween-like variety known for its vibrant orange color. These lobsters owe their color to a different gene called "Orange," which affects the production of a pigment called astaxanthin.

Found in high concentrations in shellfish, astaxanthin is a powerful antioxidant with numerous health benefits. Its vibrant hue gives these lobsters their tell-tale orange color, which is particularly prominent in the fall months when lobster meat is at its sweetest.

So, why the Halloween connection? You might be wondering. The vivid, fiery colors of these lobsters naturally evoke the vibrant hues of the jack-o'-lanterns, fall leaves, and other spooky surrounds that dominate Halloween aesthetics.

The PDQ Bash, held every year around Halloween, celebrates this connection. The festival showcases these rare, colorful lobsters, serving up lobster dishes, and even featuring a costume contest with a lobster theme!
