Precisely, yes; crabs do lay eggs. The egg count may vary around 50,000 to 10 million eggs depending on the type of crab species.

Where do crabs lay their eggs?

Eggs are fertilized as they pass out of the crab’s body and are deposited under the apron. The apron is actually the curled-under abdomen, and has small appendages to which the eggs attach. Egg masses have an average of two million eggs, and can have up to eight million eggs.

Crabs brood their eggs for about two weeks and will hatch once the spongy egg mass darkens from yellow into a chocolate brown color. “Probably one or two survive,” said Roman Jesien, a science coordinator with the Maryland Coastal Bays Program.

Do crabs lay eggs on the beach?

During spawning, the female crab partially buries herself in the sand while she deposits a cluster of about 4,000 tiny green eggs. In an evening of egg laying, a female crab can lay several egg clusters, and she may spawn repeatedly over several nights to lay 100,000 or more eggs.

The male transfers sperm by inserting his gonopods (sexual organs resembling antennae) into the two genital pores, called gonophores, on the female’s underside. The female stores the sperm in a storage sac called a spermatheca until she is ready to use it.

Do crabs feel pain?

A longstanding related question: Do they feel pain? Yes, researchers now say.
