A freshly laid lobster egg is the size of the head of a pin (1/16").
Lobster eggs are indeed about the size of the head of a pin. A female lobster carries about 8000 eggs inside for 9-12 months, then another 9-12 months under her tail. Fishers have to return lobsters to the water that have visible eggs under their tail as part of fishery conservation methods. And from every 50,000 eggs, only two lobsters are expected to survive to legal size.
