Lobsters are born from eggs.   For most females, the eggs will be laid the year after mating. The eggs are fertilized outside the female when the eggs are laid. After t â¦ hey're laid, the eggs remain attached under the tail, on the pleopods, by a kind of sticky substance. The female then keeps her tail folded up under her and carries her eggs for almost a year (between 9 and 12 months).
