Biological reproduction:

The breeding speed of king crabs is amazing, and each female crab can produce nearly 10 thousand live crabs every year. King crabs usually lay eggs in shoals about 350 meters away from April to June every year. Most of these creatures live in shallow mud and inhabit the Barents Sea and its southern waters.

During the breeding season, the female king crab and the male king crab hatch after mating. Generally speaking, the growth period of king crab is 4 years in its life span of about 30 years.

The hatching rate of eggs is about 16000/80000.
