egg-bearing female crab Red king crab, like this egg-bearing female, once thrived in the cold, clear waters around Kodiak Island. State, federal and university scientists hope to cultivate king crab in hatcheries in numbers large enough to rebuild wild populations.

Red king crab and blue king crab eggs

General caption: Viewed through a microscope, eggs of red and blue king crab from adult broodstock collected last summer from waters around Kodiak Island and the Pribilof Islands show distinct eyes of larvae inside. Hair-like strands extend from the eggs to help them attach to the underside of the adult female. Although initially difficult to recognize as crab, the tiny larvae will within about five months after hatching molt into the first juvenile crab stage with distinct legs and claws. (Photos courtesy Celeste Leroux, Alaska King Crab Research and Rehabilitation Program, Alaska Sea Grant.)

Red king crab eggs Now only about the size of a pinhead, the red king crab larvae inside these eggs will take about eight years to become harvest-size crab, among the world’s largest crustaceans. The hair-like strands that extend from the eggs help them remain attached to the underside of the adult female during their development.

Glaucothoe

King crabs spend their first several months in the plankton as larvae. This late stage larva is called a glaucothoe and is the last larval stage before the crab settles to the bottom and becomes a juvenile. (Photo by Celeste Leroux.)
