Lithodes aequispinus, the golden king crab, also known as the brown king crab, is a king crab species native to the North Pacific. [2] Golden king crabs are primarily found in the Aleutian Islands and waters nearer to Alaska and British Columbia; their range also extends to the Russian far east and Japan, albeit with a less dense population.
The phylogeny of king crabs as hermit crabs who underwent secondary calcification and left their shell has been suspected since the late 1800s. [4] They are believed to have originated during the Early Miocene in shallow North Pacific waters, where most king crab genera – including all Hapalogastrinae – are distributed and where they exhibit a high amount of morphological diversity.
Much of this foreign crab is reportedly caught and imported illegally and has led to a steady decline in the price of crab from $3.55 per pound in 2003 to $3.21 in 2004, $2.74 in 2005 and $2.30 in 2007 for Aleutian golden king crab, and $5.15 per pound in 2003 to $4.70 in 2004 to $4.52 in 2005 and $4.24 in 2007 for Bristol Bay red king crab.

Earlier this year, the U.S. Department of Commerce allocated almost $192 million to assist fishers affected by the closures of the red king crab and snow crab fisheries in 2021 and 2022, but some ...
The ocean around Alaska is now becoming inhospitable for several marine species, including red king crab and sea lions, experts say. A warmer Bering Sea is also ushering in new species ...
The red king crab is the most coveted of the commercially sold king crab species, and it is the most expensive per unit weight. It is most commonly caught in the Bering Sea and Norton Sound , Alaska, and is particularly difficult to catch, but is nonetheless one of the most preferred crabs for consumption.
Red crabs have only been commercially fished for about 30 years, so little is known about their biology and reproduction. The National Marine Fisheries Service has deemed them a data-poor stock.
A red king crab. The example of king crabs (family Lithodidae) evolving from hermit crabs has been particularly well studied, and evidence in their biology supports this theory. For example, most hermit crabs are asymmetrical, and fit well into spiral snail shells; the abdomens of king crabs, even though they do not use snail shells for shelter ...
