Do Isopods Lay Eggs or Give Birth? Discover the Truth

Isopods are small tiny creatures that mostly live in water but are also found on land. The isopods living on land are called terrestrial isopods and the ones living on the land are called marine isopods.

We humans are very familiar with isopods and have a growing interest in isopods. Most of the people, who love aquatic life are also in search of how the isopods reproduce and do they lay eggs or give birth.

Isopods reproduce through sexual reproduction means they mate to transfer sperm from male to female following the process of mating. Female isopods have a special pouch called marsupium which protects the developing eggs.

If you have the question “Do isopods lay eggs” in your mind and want to learn about the reproduction and life cycle of isopods. You are at the right place.

Here I have discussed all the important information about the reproduction and the life cycle of the isopods.

Do Isopods lay Eggs or Give Birth

there are many species of isopods having different characters but the most common thing in all types of isopods is their reproductive system. Most of the isopods lay eggs and are called oviparous. Female isopod releases the eggs from their marsupium after the development of the isopod’s eggs.

isopods lay eggs or give birth

The eggs of isopods take 3 to 4 weeks to hatch. Female isopods have the special adaptability to protect isopods eggs from the environment and other predators.

Most of the isopods reproduce throughout the year while some isopods have season to lay eggs. It depends on some factors like temperature and humidity. Some isopods lay eggs in the early summer due to high humidity.

The reproductive process of isopods

The process of reproduction in isopods starts with a mating process where male and female isopods come together for reproduction. This involves the transfer of sperm from male to female through their reproductive parts.

Isopods undergo internal fertilization and the transfer of sperm usually occurs via spermatophore (a packet of sperm cells).

The underside of the female isopod contains the marsupium (egg pouch). After mating the female isopod moves the fertilized eggs to the pouch for protection and development.

The developed eggs are then released outside the body in a sustainable environment for further development.

Then the developed eggs are hatched in a specific period and shed their exoskeletons as they grow.

Reproduction habitat for pet isopods

If you are planning to pet isopods or raise them for commercial purposes, the first thing that comes to your mind is the habitat for the isopods where they can reproduce. Usually, pet isopods are kept in a container made of glass or plastic. You will just need sand, clay, or coir fiber if you do not have sand near you.

You must add tree bark and leaves to the container but the leaves should be dried at 200 degrees Fahrenheit for 5 to 10 minutes.

Isopods like a damp place for lying eggs so use a spray bottle to dampen the bed.  After a few days you will see that the isopods have laid the eggs in the container.


What do isopod eggs look like

isopod eggs look like small round or oval-shaped white structures. These eggs are often semi-translucent means you can see the developing embryo inside. The size ranges from 1 to 3 millimeters in diameter.

Can you eat isopod eggs?

No, isopods are not commonly consumed by humans, so their eggs are not supposed to be eaten. Another reason is that they are too small to be eaten. But some small animals consume isopod eggs.

how long does it take for isopod eggs to hatch?

it depends on the species of the isopods but most commonly it takes 3 to 4 weeks or sometimes more than that to hatch. But again safety is very important for the eggs to be hatched so they are kept in the egg pouch. Eggs are hatched if they are properly developed.

How many times do isopods lay eggs?

Isopods lay eggs twice or thrice a year. Female isopod lays a bunch of eggs at a time and the amount is about 300 eggs. These eggs are then developed under the marsupium for safety and then hatched after a few weeks.

How long are isopods pregnant?

The pregnancy of isopods lasts for about 40 days which includes many processes like mating, internal fertilization, egg development in the marsupium, and hatching.


Hopefully, you will now be familiar with the reproductive process of isopods. This piece of content has covered all the basic information you need to know about isopod eggs and the reproduction process.

So the question was do isopods lay eggs or give birth? You will now know to implement in case if you want to keep isopods as a pet or for other commercial use.

I hope you got it. Let me know if you have any queries about this topic.
