Lobster Fact:
Lobsters may take five to eight years to reach sexual maturity. The female sex organs, called the ovaries or “coral,” are two cylindrical rods traversing from the middle of the body to the tail. The openings from the ovaries to the outside are located on the basal segment of the third walking legs. The female has a seminal receptacle on the ventral surface near the junction of the thorax and abdomen, which stores viable sperm up to two years after mating. Lobsters mate seasonally, generally just after the female molts. The female releases a continuous stream of eggs from the oviduct openings. As the eggs pass the seminal receptacle, they are fertilized; covered with a glue-like substance; they stick to each other and the swimmerets. The female protects her eggs from predators, keeps them clean, and oxygenates them for nine to eleven months. When the eggs are ready to hatch, the female walks into the current, un-cups her tail, and vigorously waves her swimmerets, which frees the free-swimming larvae into the water. She releases them a batch at a time, a practice that increases their chances for survival.
