Crabs lay eggs on the beach when there’s a full moon as the water level gets to its highest peak. It’s undoubtedly one of the most fascinating phenomena of sea creatures as a female crab only lays eggs once in her lifetime.
But there are a lot of misinformation and confusion about the birth process and reproduction of crabs. That starts from where they lay eggs, how often they do so, how many eggs they lay at once, and how many of them actually grow to live.
Below, we’ll cover more about where do crabs lay eggs and more about the process so that you can get a better understanding of it. Without any further ado, let’s dive into the deeper discussion.
Do Crab lay Eggs or Give Birth
Crabs lay eggs to reproduce and they don’t give birth. They are like most other sea creatures and fishes that lay eggs to hatch the babies. However, crabs are quite fascinating as their eggs laying process is quite interesting.
They lay the eggs when the water level gets higher, which is on the full moon. The female crab rises to the highest water level and has a male crab clinging onto her during that time.
Do Crabs lay Eggs on Land or in Water
Crabs lay their eggs on dirt or coastal rock burrows at the beginning phase. Once they are done with laying the eggs, they sit there for 2 weeks until the eggs are hatched. The eggs are typically hatched in the late summer.
Once the hatching process is complete, they return to the habitat. So, as you can tell, crabs lay their eggs on land as the typical optimal place for them is dirt or coastal rock burrows.
How many eggs do crabs lay at a time
There is no exact number when it comes to how many eggs crabs lay at a time as it differs from scenario to scenario. However, a female egg mass can contain up to 2 million eggs in the sack, which is an average number. But that number can even exceed 8 million as well, which is quite fascinating.
From those, the female crabs only lay around 20000 eggs. And even from these only a few can survive as the rest gets eaten by fish or don’t hatch.
Do all crabs lay eggs
All crabs lay eggs as they are oviparous beings. They reproduce by laying eggs and that’s how they leave their offspring in the sea world. For crabs, the time between February to April is the time of mating and reproducing. And then they start laying eggs somewhere between April and May.
The number of eggs produced by crabs varies from their subspecies and depends on a lot of variables. But they do it once in a lifetime and that’s how they keep themselves from getting instinct.
Do crabs carry their babies
Crabs don’t carry babies and they only carry fertilized eggs. The sperm from male crabs are deposited in the female sack, where the eggs are fertilized when the female is ready. Then the female crab carries the egg mass, which carries millions of eggs. That can last for weeks and when the time is near, the female crab leaves for the ground to lay the eggs. Finally, they lay the egg and stay there for around 2 weeks until the eggs are hatched.
How often do crabs lay eggs
Crabs only lay eggs once in their lifetime, which is pretty unique. That allows them to produce their offspring and leave it in the sea world. What’s even more fascinating is that they only lay around 20 thousand eggs during that period.
However, only 2 or 3 crabs live to grow up from all the 20 thousand eggs. The rest either gets eaten by the fishes or don’t hatch. That’s the rate they reproduce and this process is keeping the crabs from going instinct and balancing the Seaworld.
Where do blue crabs lay their eggs
Blue crabs lay their eggs as same as the other subspecies of crabs. However, that is quite fascinating on its own as the process is quite extraordinary to see in the sea world.
The fertilized eggs get deposited under the apron of the female crab’s body. It’s an abdomen part of the female crab where the egg mass gets stored. It contains millions of eggs, which can be somewhere from 2 to even 8 million.
Once it’s time to lay the eggs, they rise to the top of the waterline and go to ground level. Then they lay the eggs on dirt or coastal rock burrows to keep the eggs protected. Then the female crab sits there for the eggs to hatch for about 14 days or so.
How do crabs have babies
Like most other sea creatures, crabs lay eggs to produce babies. These eggs are fertilized in the female crab’s body and these can be found under the apron of its body. The apron itself is an abdomen part and contains small appendages. These appendages carry those eggs as the eggs get attached to them.
Also, the mass of the eggs can differ from case to case. In most scenarios, the egg masses can have around 2 million eggs in them, which is the average case. However, it can have over 8 million eggs as well depending on the scenario.

Hopefully, now you have a greater idea about where do crabs lay eggs and more about the entire process. As you saw, it’s a quite fascinating creature that has a very interesting reproducing cycle.
As a female crab only can produce 2-3 crabs in her lifetime, it’s our duty to save the sea world and to make it a safer habitat for the crabs to grow. That will make sure that this sea creature doesn’t go instinct anytime sooner and can grow in number.
