Hermit Crab Without Shell

The hermit crab that doesn’t have a shell on its back will be covered in this article. You will discover how crucial the shell is to the life of this particular Hermit Crab Without Shell. We will discuss the reasons behind hermit crab shell sheds and the problems that can occur when a crab lacks a shell face.


A little about Hermit Crab

The families Paguridae and Coenobitidae include hermit crabs. These crabs seek sanctuary in hollow items such as empty snail shells (such as whelk or periwinkle) for physical safety as well as partial containment. Because their bodies lack a protective shell, they are extremely open to attack by predators.
Although they are rarely seen on land or in trees, hermit crabs are aquatic animals that inhabit environments with sand or mud bottoms.

Problems with Hermit Crab without Shell Face:


A hermit crab’s exoskeleton becomes extremely dry and brittle in the absence of a shell, making it more susceptible to the elements. Crab keepers can help their pets discover new homes before their physical condition decreases.
In addition, hermit crabs seek cover within their shells. Crabs are protected from other potentially fatal situations when they are concealed within their shells. Put another way, we may say that a particular crab’s life is guaranteed by its shell.

The Significance of a Shell for Hermit Crab

A hermit crab’s abode is a shell. These shells are necessary for hermit crabs to keep their bodies from losing too much water. Hermit crabs are unique in that they have to find and use the shell of another species. A hermit crab carries about this “borrowed” shell, which it utilizes to manage and contain moisture as well as shield its delicate abdomen.

Why do some hermit crabs not have shells?


Shell evacuation happens when a developing crab has to “trade up” its exoskeleton and housing to fit its larger body size. It’s not a big deal because this is just the natural molting process. But not every crab that sheds its shell is going through a molt. There are several reasons why a hermit crab can emerge from concealment, including as stress, an unwelcoming environment, an ill-fitting body, fungus, or unexpected visitors. The homeless crab’s health is harmed by the rapid exposure to its environment.

7 Reasons for Hermit Crabs to Change Their Covers


They change the covers for a number of purposes. However, we shall explain the seven reasons hermit crabs depart from their shells or alter them.

For Protection

Hermit crabs are nocturnal animals that, like snails, carry their dwellings on their backs. Unlike snails, which make their own shells, hermit crabs use an old animal shell, such as a sea snail. When threatened, the hermit crab can withdraw inside itself. A hermit crab will seek out a larger shell when it outgrows its current one and will swiftly crawl out of the smaller one and into the new one.

Universal Substitution

The Hermit Crab occasionally sees something that they think would be a better fit for them than what they currently have. On the other hand, this process moves along quickly and uninterrupted.

Change in size

You probably already know that hermit crabs only live for 15 to 20 years if you possess one. It must therefore be removed and replaced with a larger one. It’s similar to how people buy new clothes when their sizes change.

Invasion from within their shell

An other hypothesis is that the object inside the shell is alien debris.It could be tiny fragments of gravel, a parasite that resembles a mite, or even a bacterial or fungal infection. This could agitate the crabs to the point where they have to go to a different location.
This mostly happens when appropriate safeguards are not taken. By keeping illnesses at bay, clean water and nutritious food can help your crab from getting sick.

Searching for a better environment

One of the most common mistakes is establishing the environment incorrectly. For the hermit crab to be healthy, the temperature and humidity must be kept within a certain range. Hermit crabs are known to be happy in favorable environments, and variations in the atmosphere are a major contributing factor for these particular insects to frequently replace their shells.

They might be ill

There can be a disease or another issue affecting your hermit crab. It often happens that people have fatal diseases. One of these is shell rot, which kills victims and leaves holes in their bodies.
Hermit crabs may even come out of their shells under these circumstances because it is difficult for them to remain within. Additionally, because the inside of the body is warmer than the outside, bacteria can spread throughout it.

Pollution from microplastics

Plastic waste was everywhere to be seen on the beaches. As demonstrated in this instance, microplastic pollution affects the crab’s choice of shell.Sometimes a crab will mistake a plastic object for anything else, but eventually it will become clear to them what it is. Consequently, picking the right home for protection gets challenging.


We read these passages together and then discussed about a specific kind of crab that has no shell on its back. Shell-free hermit crabs are the only ones in their environment. They relocate for a variety of reasons, some of which are basic and covered in the reading above. Hermit crabs cannot survive without their shells, and they cannot live without them for their whole lives. In order for hermit crabs to survive and continue to be around, sufficient care must be given to them.
