help Blue King Crab FAQ
Where are Blue King Crabs primarily harvested?
Blue King Crabs are large decapods primarily found in the cold waters of the North Pacific Ocean, particularly around Alaska and Russia. In the United States, they are most famously harvested near the Pribilof Islands and St. Matthew Island.
What distinguishes the Blue King Crab from the Red King Crab?
Before cooking, the Blue King Crab features a distinct brownish-blue shell with a notably oversized right claw, whereas the Red King Crab has a more uniform reddish-brown appearance. The Blue King Crab also generally has a slightly spikier shell texture.
Why is the right claw of the Blue King Crab so much larger than the left?
The male Blue King Crab has one massively enlarged right claw, known as a crusher claw, which it uses for crushing the thick shells of its prey. The smaller left claw, called the cutter claw, is used for tearing flesh.
Do Blue King Crabs turn red when cooked just like other crabs?
Yes, despite having a brownish-blue shell while alive, the Blue King Crab turns a vibrant, bright red when cooked. This color change occurs because heat destroys the protein binding the blue pigment, leaving only the red astaxanthin visible.
