opilio crab

Opilio crab, also known as snow crab, refers to the "real" or "true" crabs. As befits a crab, it has a body covered with a strong shell and 5 pairs of walking legs.

Opilio crab: Introduction

The common snow crab or Opilio crab (lat. Chionoecetes opilio) is a species of crustacean that lives in the seas of the Northern Basin at a depth of 50 to 400 meters. Originally, Opilio crabs were found only on the Pacific coast of Kamchatka, but over time it spontaneously populated the eastern part of the Barents Sea and some other regions, for example, the northern territorial waters of Canada. Opilio crabs were first discovered in the Barents Sea in 1996.

Although no special measures were taken to populate the snow crab in the northwestern seas, it coped well with this task on its own. Opilio larvae «moved» to the Barents Sea in the ballast waters of ships.

The snow crab is much smaller than the famous King crab: while King crabs can weigh 10 kg or more, even the largest male Opilios rarely reach a mass of 3 kg. Opilio females are twice as small as males.

Crab Parts

The body of the Opilio Crab consists of a head-chest and five pairs of limbs. The cephalothorax is covered with a chitinous shell, a carapace. The shell is smooth, without spikes and outgrowths typical for Red King Crab. The carpax protects the internal organs and maintains the proportions of the pear-shaped body. The first pair of limbs ends with powerful claws that help to capture and grind food.

More about the snow crab

The courtship ritual is interesting: a male snow crab grabs a female with the front pair of "legs" and literally "carries her in his arms" for about two weeks. All this time, the male is starving, because his claws are busy. The female also has a hard time – she changes her shell, sheds, while staving off less fortunate gentlemen at the same time. After fertilization, the female hides 150,000 eggs in special holes on her swimming legs, where the kids "ripen" from one to three years. At this moment, "the groom" literally leaves his chosen one. In most cases, he goes to look after the next female crab, while the «pregnant» bride has to survive on her own – with a soft, not yet completely hardened, shell and a bunch of future crabs "in her arms".

The complexities of the mating ritual of snow crabs are compensated by a complete indifference towards the already hatched cubs. Tiny crabs, barely born, are washed off the mother's limbs by streams of water and set off on their first independent voyage. They will grow, molt and, if they are lucky, acquire their own offspring – but this will happen not sooner than in 4-5 years.
