The American Lobster is a species of lobster present along the Atlantic coast of North America. This is a region spanning Labrador in the north to Cape Hatteras, North Carolina in the south.
The species typically attains a length of around 24 inches (61 cm), and a weight of about 9 pounds (4.1 kg). However, individual specimens could weigh as much as 44 lb (20 kg).
In fact, this makes the American Lobster the heaviest crustacean in the ocean.
American Lobster Primary Coloring
The normal coloring of the American Lobster is a dark bluish green to greenish brown. That is a mix of yellow, blue, and red pigments.
Only about one American Lobster in 2 million possesses a primarily blue coloring. A genetic mutation causes a blue lobster to produce an excessive amount of a particular protein. The protein and a red carotenoid molecule (astaxanthin) then combine to form a blue complex (crustacyanin). Indeed, this gives the lobster its blue color.
Despite the rarity of strangely colored lobsters, many people seem to find them. Nonetheless, it is unclear as to whether this is:
- an effect of social media (i.e. it is easier to report catching a strangely colored lobster), or
- if it is due to a decrease in predator populations.
American Lobster Rarest Colors
Even rarer is an American Lobster with a primarily yellow coloring. These are the result of a rare genetic mutation and the odds of finding one are roughly 1 in 30 million.
Reports of yellow lobsters include one off Whaleback Island (at the mouth of the Kennebec River), Maine, on August 1, 2006. Since then, people have seen only three of that coloring. These include one off of Prince Edward Island, Canada, one in Kalihi, Hawaii, and one in Narragansett Bay off Rhode Island.
