How long do hermit crabs live? (Lifespan in Captivity vs. Wild)

The lifespan of an adult hermit crab is about 2 years, but they can live up to 5 or 6 years if kept properly and fed well.

A healthy hermit crab will eat small pieces of food every day. It should be given fresh vegetables such as lettuce leaves, spinach, broccoli, carrots, peas, beans, etc., once per week. If you feed it dried foods like bread crumbs, pasta, rice, crackers, cookies, chips, etc., then your hermit crab may not get enough nutrition from these dry foods. You need to make sure that your hermit crab has access to plenty of water at all times. This means keeping its tank clean and adding new water regularly. A good rule of thumb for how much water to add each time is 1/3rd of the total volume of the aquarium. For example, if your aquarium holds 10 gallons of water, then you would add 3 quarts of water when replenishing the tank with freshwater.

If you are feeding your hermit crab frozen foods, then freeze them first before giving them to your hermit crab. Frozen foods have less moisture than their raw counterparts so this could cause problems for your hermit crab’s digestive system. Also, avoid using canned foods because they contain preservatives that might harm your hermit crab.

Wild Hermit Crab Life Expectancy

The life expectancy of wild hermit crabs varies from species to species. Some wild hermit crabs can live for over 20 years. Others may die within a year. If you want to keep your wild hermit alive for a long period of time, you’ll need to feed it regularly. In addition, you’ll need to give it access to freshwater. However, if you don’t provide your wild hermit with these things, then you’ll likely see it die after a relatively short amount of time.

As mentioned above, some species of hermits can live for up to 20 years. On the other hand, others may only live for a couple of months. Some people believe that hermit crabs are born with an expiration date stamped on their shells. They think that the shell will begin to crack and fall apart once this date has passed. But this isn’t true. There are no expiration dates on hermit crabs’ shells. Instead, they start to age when they reach sexual maturity. At this point, they become sexually active. This is what causes them to shed their shells. Once they’ve shed their shells, they’ll continue shedding them until they’re dead.

In general, most hermit crabs live for around 3-5 years. However, there are exceptions to this rule. For example, some hermit crabs can live as long as 10 years. Although a hermit crab’s lifespan may vary depending upon its species, it’s important to remember that each individual hermit crab is unique. For instance, one hermit crab might live longer than another because he eats less food or because he lives in a better environment.

And It’s impossible to say which hermit crab will live longer without knowing exactly how old he is.

Captive Hermit Crab Life Expectancy

Hermit crabs can live for a very long time when they’re kept in captivity. But even though they can live for a very, very long time, they still aren’t immortal. The average life expectancy of a captive hermit crab is about 5 years.  There are exceptions to this rule, however. Some hermit crabs have been known to live for over 10 years. And some have lived for much shorter periods of time. A few hermit crabs have died within just hours of being purchased from pet stores.

They eventually die. And this happens regardless of whether they’re kept in captivity or not.  When a hermit crab dies, it usually goes through a process called molting. Molting involves shedding its exoskeleton.  During this process, the hermit crab sheds its old skin and grows a new one. This allows it to grow larger. It also makes it easier for it to move around.

Molting doesn’t happen every day. Sometimes it takes several days or weeks before a hermit crab molt. After it molts, it continues growing larger. Then, it begins to eat more food. Eventually, it reaches adulthood.  At this point, it becomes sexually mature. When a hermit crab reaches adulthood, it stops eating.

Instead, it starts mating. After mating, it lays eggs. The eggs hatch into baby hermit crabs. Then, the babies go through molting. They grow bigger and stronger. Finally, they reach adulthood. Once they reach adulthood, they stop eating. They also stop breeding. This means that they’re ready to be released back into the wild.

So, while hermit crabs can live for many years in captivity, they won’t live forever. They’ll eventually die.

Hermit Crab Life Cycle Explained

When a hermit crab reaches adulthood, it will start mating. The male hermit crab will release sperm into the female’s genital opening and she will store it inside until she needs it later on. When the time comes, the female hermit crab will lay eggs in the sand or gravel substrate in her home burrow. She will then cover the eggs with more sand or gravel so that no predators can find them. Once the eggs hatch, the baby hermit crabs will crawl out of the nest and begin exploring their surroundings. They will continue to grow and develop over the next few months. Eventually, they will become full-grown adults, around one year old. At this point, most hermit crabs will leave their parents’ burrows and seek out their own homes. However, some hermit crabs will remain with their parents until they die.

Hermit Crabs Reproduction: How Do Hermit Crabs Mate?

Hermit crabs mate by releasing sperm into the female’s genitals. Afterward, the female stores the sperm inside her body until she wants to reproduce again.

Hermit Crab Life Cycle – Duration of Mating Process

Mating takes place after the hermit crab has reached sexual maturity. During mating, the male releases his sperm into the female’s reproductive tract. Afterward, the female stores the semen inside her body until she decides to reproduce.

Breeding and Gestation

When it comes to breeding and gestation, hermit crabs are very similar to other animals. The main difference between hermit crabs and other animals is that hermit crabs are born alive. They hatch out of eggs and begin life as independent creatures.

Gestation usually lasts about three months. During this time, hermit crabs feed on each other until they reach adulthood. After reaching maturity, hermit crabs mate and lay fertilized eggs.

After hatching, hermit crabs go through four stages of development:

1. Embryonic Stage – During the embryonic stage, hermit crabs undergo rapid growth. Their bodies increase in size by 50% every two days. At this point, they are called nauplii.

2. Nauplius I Stage – Once hermit crabs reach the nauplius I stage, they start feeding on algae. They continue to grow rapidly and eventually become juvenile hermit crabs.

3. Juvenile Stage – As they grow larger, hermit crabs move into the juvenile stage. While in this stage, they continue to consume algae.

4. Adult Stage – When hermit crabs reach the adult stage, they stop eating algae and instead consume meaty foods such as shrimp.

Hermit Crab Lifespan in Captivity

Most hermit crabs reach sexual maturity within two years of being born. There are many factors that affect the lifespan of a hermit crab including the size of the aquarium, temperature, humidity, diet, etc. Some hermit crabs can live longer than others depending on what conditions they are living under.

What Are Some Common Problems That Can Occur With Hermit Crabs?

There are many common problems that can occur with hermit crabs. Here are some of the most common ones:

1. Shell Disease – Shell disease is caused by bacteria. The bacteria enter into the shell through tiny cracks in the shell and multiply inside the shell. When the bacteria reach a certain level, they start producing toxins that damage the shell. Eventually, the shells become brittle and break apart. As a result, the hermit crab loses its ability to protect itself.

2. Parasites – Parasites are also very common among hermit crabs. They usually attach themselves to the hermit crab’s gills and slowly drain its blood. Once the hermit crab starts losing blood, it becomes weak and eventually dies.

3. Deformed Shells – Sometimes, hermit crabs develop deformed shells. These shells often look different from normal shells. In addition, they sometimes grow abnormally large. However, there is no way to know whether or not this problem is hereditary unless you have siblings who don’t have deformities.

4. Malnutrition – Another common problem with hermit crabs is malnutrition. Because they eat only small amounts of food, they can easily starve to death. To prevent this from happening, you must provide your hermit crab with fresh vegetables and other types of food on a regular basis.

5. Sudden Death – Finally, sudden death is another type of problem that can happen with hermit crabs. Usually, this happens when a hermit crab gets caught in the wrong place during cleaning.

6. Diseases – There are several diseases that can affect hermit crabs. One of the most common is bacterial infections. Bacterial infections can lead to severe illness and even death.

7. Overcrowding – Overcrowding is another common problem that can happen with any pet. Too many hermit crabs in one space can cause stress and aggression.

8. Trauma – Sometimes, hermit crab owners accidentally injure their pets. This can happen when they drop their pets onto hard surfaces or knock them against objects.

9. Predators – Predators can also attack hermit crabs. Most predators are fish, but others include birds, snakes, and dogs.

10. Other Problems – There are many other problems that can happen with hermit crabs. Some examples include:

– Anemia – Anemia occurs when a hermit crab doesn’t get enough iron in its diet. It causes the hermit crab’s muscles to lose strength.

– Cancer – Cancer is another serious problem that can occur with hermits crabs. If a hermit crab has cancer, it will likely die within a few weeks.

– Heat Stroke – Heatstroke is also a dangerous condition that can happen with hermit crabs. If a hermit crab suffers heatstroke, it will experience extreme pain and convulsions.

– Heart Attacks – A heart attack is a health issue that can be fatal if left untreated. This is especially true for hermit crabs whose hearts are still developing.

– Infection – Infection is yet another common problem that can occur with a hermit crab. Some of the more common infections include salmonella poisoning and tetanus.

How Do You Know Whether Or Not Your Hermit Crab Is Healthy?

The easiest way to tell if your hermit crab is healthy is to look at its eyes. If the eyes appear dull and lack color, then your hermit crab probably isn’t feeling well. On the other hand, if the eyes appear bright and colorful, then your hermit is doing fine.

How Long Can a Hermit Crab Live Without Food?

To determine how long a hermit crab can survive without food, you should first figure out what kind of hermit crab you have. Then, you’ll need to find out how much food your hermit crab needs each day. Once you’ve figured all of this out, you’ll need to make sure that you feed your hermit crab every single day.

If you don’t give your hermit crab enough food, he will eventually begin to suffer from malnutrition. When this happens, he may become weak and sickly. He could even start to develop anemia. In some cases, this can lead to his death.

Malnutrition is a very serious problem because it can result in a lot of different health issues. For example, malnutrition can cause a hermit crab to become anemic. Anemic hermit crabs usually have pale-colored blood. They’re also prone to infection and inflammation.

In addition to being malnourished, a hermit crab who becomes too thin can also suffer from heatstroke. Heatstroke is a life-threatening condition that can quickly kill a hermit crab.

How Long Can a Hermit Crab Live Without Water?

You should know how long a hermit can live without water before purchasing one. The answer depends on the type of hermit crab you buy.

For instance, most hermit crabs can survive up to three days without water. However, there are exceptions. For example, some species of hermit crabs can only survive for about 24 hours without water.

Most hermit crabs are able to survive for a couple of days without water. However, if you want to keep your hermit alive longer than two days, you’ll need to provide him with fresh water.

Water Sources for Hermit Crabs

Hermit crabs love freshwater. But they also enjoy drinking salt water as well. So, when you’re buying a new hermit crab, you’ll need to decide whether or not you want to purchase a freshwater or saltwater hermit crab.

Freshwater Hermit Crabs

When you purchase a freshwater hermit crab, you should make sure that you get one that’s been raised by someone else. Otherwise, your hermit crab might end up getting sick.

There are several reasons why you shouldn’t try to raise your own hermit crab. First of all, raising a hermit crab is a difficult process. It requires lots of time and patience. Secondly, you won’t be able to ensure that your hermit crab gets proper care.

On top of that, you’ll need to worry about the possibility of losing your hermit crab. Because hermit crabs are so small, they tend to escape easily. And once they escape, they often wind up living in places where they aren’t wanted.

Saltwater Hermit Crabs

A saltwater hermit crab is going to require a little bit more work than a freshwater hermit crab. But the benefits far outweigh any extra effort required.

First of all, you’ll be able to ensure that you get a healthy hermit crab. If you purchase a saltwater hermit crab, you can rest assured that he’s going to stay healthy.

Secondly, you’ll be able to get a hermit crab that’s already grown up. This means that you won’t have to worry about having to raise your hermit crab. You can simply take him home and let him grow up.

Thirdly, you’ll be able to save money. A saltwater hermit crab isn’t going to cost you nearly as much as a freshwater hermit crab does.

And finally, you’ll be able to find a variety of different kinds of saltwater hermit crabs at pet stores. These include:

• Pagurus bernhardus

• Coenobita clypeatus

These are just a few examples of the many different types of saltwater hermit crab available. There are dozens of other kinds available as well. So, if you want to buy a saltwater hermit, you’ll have plenty of options.

How to Make Your Hermit Crab Live Longer

What Makes Them Die Young?

The first thing you should know about hermits is that they die young. In fact, they die within their first year.

However, this doesn’t mean that you can’t keep them alive for very long. There are ways that you can extend their life expectancy. The trick is knowing what these methods are.

Why Do They Die So Soon?

The reason that hermit crabs die so soon is that they don’t have enough food. When they eat too little, their bodies start breaking down. Their shells become brittle and break off.

This causes them to lose weight and eventually die.

How Can You Help Them Eat Better?

You can help your hermit crabs by feeding them better. You can feed them with fresh vegetables and fruit.

Hermit crabs love to eat lettuce, celery, and carrots. They also enjoy eating apples and bananas.

You can even give them some shrimp or lobster meat. However, you should never feed them anything that has been frozen. Frozen foods contain chemicals that can harm your hermit crabs.

You can refer to this article for the hermit crab food list.


If you want to keep your newly purchased hermit crab alive for a very long time, you’ll need to make sure that it has access to freshwater. However, you don’t necessarily need to give your hermit crab fresh water every day. As long as you feed him regularly, he’ll be fine.  And it’s important to remember that hermit crabs like their food to be soft. So, if you’re feeding them dry food, you’ll need to soak it first.

In addition, you’ll need to clean out their tank frequently. This will help prevent bacteria from building up inside of the tank. Finally, you’ll need to check the temperature of the water periodically. If the water is too cold, your hermit crab may freeze.

If you follow these tips, you’ll be able to keep your hermit crab alive for an extended period of time.
