When you hear 'Alaskan king crab,' chances are you picture something truly colossal, a majestic crustacean worthy of its regal title. And you wouldn't be wrong. These giants of the northern Pacific are renowned for their impressive size, a key reason they've become such a sought-after delicacy.
But here's a little secret: 'Alaskan king crab' isn't just one single entity. It's more like a royal court, with different species vying for attention, each with its own characteristics, including size. The undisputed heavyweight champion, and the one most people think of, is the Red King Crab (Paralithodes camtschaticus). This is the most abundant species, making up the lion's share, around 70% or more, of the commercial catch. They are the true titans, often boasting the largest leg span and weight, making them the quintessential 'king' of crabs.
Then there's the Blue King Crab (Paralithodes platypus). While still a substantial crab, they tend to be a bit smaller than their red cousins. They're also a rarer catch, partly due to their lower reproductive rate. This scarcity, coupled with their formidable presence, adds to their allure, though they might not reach the absolute gargantuan proportions of the largest red kings.
Finally, we have the Golden King Crab (Lithodes aequispinus), also known as the Brown King Crab. These crabs often have a more elongated body and can grow quite large, though their leg span might not always be as dramatically wide as the red king crab. Their appearance is distinct, often with a more golden or brownish hue, setting them apart visually.
So, while all these species hail from the rich Alaskan waters and are considered 'king crabs,' their size can vary. The Red King Crab generally takes the crown for sheer bulk and impressive leg spread, making it the benchmark for 'Alaskan king crab' size. But the blue and golden varieties offer their own unique appeal and impressive stature, contributing to the diverse and fascinating world of these magnificent crustaceans.
