Eggs, eggs and eggs, a female lobster with a healthy amount of fertilized eggs. It’s usually illegal to harvest a mother-to-be like that one in order to keep the wild population up. Lobster fishermen will only keep females when the eggs are still inside and not visible.
The females carry thousands of tiny black eggs inside for a year and then outside for another year tucked under the swimmerets on the tail’s underside. Those eggs look large and may have been ready for release as larvae. My guess is, when the lobster is cooked the eggs turn pink.
