How to Determine if a Hermit Crab is Dead or Just Molting

In recent years, hermit crabs have been a popular pet because they are easy to care for, docile, and interesting to watch. These cute crabs can live on the ground, with their empty shells as shelter and homes. With proper care, hermits can live up to 15 years. They are social crabs who enjoy being with other species.

Hermit crabs molt frequently, so they can look very limp and lifeless during this time. Many inexperienced owners assume that their pet is dead. Even experienced owners may not be able to tell the difference. It’s normal to wonder if your crab has died if there is no movement for a few weeks or days.

However, there are some simple ways to determine if your Hermit crab is sick. This article will explain how to tell if your Hermit crab is molting or has escaped. Let’s get started!

A Hermit crab’s natural, vital life stage is molting. A Hermit crab’s skin is similar to that of reptiles. They need to shed their exoskeleton. A Hermit adult will molt approximately once every 18 months, but it may molt more often before becoming an adult. The length of the process can vary from one crab to another. However, the bigger the Hermit is, the more time it takes.

The process may take between 4-8 weeks for a crab of average size. During this time they might be almost immobile. They can become stiff and unable to stand or move, so they are easily mistaken for dead.

You should not try to interfere with the process. Also, don’t pick up your crabs or assist them in any way. This could cause serious injuries. Here are some simple signs that your Hermit is getting ready to molt. These are the signs that your Hermit is getting ready for molting.

Digging

Because hermits often dig into the soft sand when they molt they are more likely to do so during the entire process. If you notice this, it’s worth checking the temperature of your aquarium. They may be trying to escape from poor conditions.

Appetite increases

Hermit crabs won’t eat much during molting, so they will eat more right before it begins. This is to store extra nutrients and fat. This is because Hermit crabs are nocturnal so it may not be obvious.

Color change

The exoskeleton of your Hermit will turn a duller color before molting starts to an almost translucent, ashy tone. Their eyes might also appear dull. Although this is often the case, their claws and tips can become white.

Regeneration of limbs

Your Hermit crab may start to grow new limbs if they are missing any of its limbs. This happens just before the molting process. These new limbs are gelatinous protrusions that will slowly expand and become the crab’s new limb after molting.

Stress

Hermit crabs will often hide under the substrate of their tanks when they feel stressed or threatened. This is more common in Hermit crabs who have just been introduced from another environment. It may take some time for them to get used to it. You should be aware that they may exhibit some of the same symptoms as molting such as lethargy and decreased appetite. They may take up to a week to adjust.

Is my Hermit crab dead?

As with all pets, there will be a point when your crab won’t be molting or hiding from the world. If your Hermit crab is not eating or moving for some time, you should first smell them. A dead crab will produce a fishy, foul-smelling odor. However, it is not always a good sign. They may also smell when they molt, but not as strongly.

Their body will also be visible partially exposed to their shell. This is normal during molting. However, if you closely examine a molting crab you might notice slight signs of movement like twitching. If there is no movement or a foul odor, it is likely that your crab has died. However, it is important to not rush to make a decision as many people mistake a molting for one that is dead.

Because Hermits are nocturnal animals, you might not be able to see them moving during the day. You should inspect your crab for tracks and other signs of movement. However, you shouldn’t attempt to move them until they are dead. If mold starts to appear, that is the only way to determine if your crab has died. To be safe, assume your crab has been molting for at least 2 to 3 months. If you see mold, it is likely that your crab has died.

Last Thoughts

Hermit crabs molt approximately every 18 months. If you pay attention to the signs, you can usually tell when they’re about to start the molting process. You may not have seen the first signs. In that case, it is best to assume your crab is molting and not dead. If your crabs haven’t moved from their substrate in 2-3 months, and you smell something fishy or rotten, it is most likely that they are dead.
