SIZE:
Approximately 25 cm for 1.7 kg.
LIFE EXPECTANCY:
At least 50 years.
LIFE CYCLE:
Reproduction takes place belly to belly. The female will keep the sperm from a single mating for two or three fertilizations. Depending on her size, she can lay thousands to tens of thousands of eggs. She keeps them beneath her tail for 9 to 12 months, until they hatch in summer. The larvae stay at the surface to feed, returning to the bottom after three to six weeks. They then measure 15 mm.
The lobster then grows by molting. It will reach its adult size in 5 to 7 years. It grows faster in warmer waters.
