SIZE : 15 cm wide, 90 cm span.
LIFE EXPECTANCY : From 12 to 13 years.
LIFE CYCLE : Sexual maturity at around 5 cm wide for the female and 9.5 cm for the male.
Reproduction takes place in winter and spring, after the female has molted.
Females choose their partners. Males will fight for their favors and protect them from predators.
Females produce between 16,000 and 160,000 eggs, which they protect under their bellies. These hatch up to two years later, between the months of April and June. The larvae drift in the water column for 2 to 8 months. Once their shell reaches 3 mm, they settle to the bottom and begin their series of molts in order to grow, until the final, terminal molt.
