Well, hermit crabs can burry themselves for fun, to distress, to molt, or just to sleep. They do this in the wild and nothing will stop them from doing it in captivity. They can do this for days, weeks, or even months without dying. Do hermit crabs leave their shells when they molt? They will completely loose their outer shell and shed it and grow a new skin which hardens to a shell.
Their exoskeletons are usually found near the molting crab. Hermits need to be left alone during this very vulnerable time and they should not be disturbed during the entire molting process. How long does it take for a hermit crab to molt? The time it takes for a crab to complete a molt varies. As a general rule, the larger the crab, the longer the whole process will take. It is not unusual for an average-sized crab to spend about four to eight weeks going through the whole process, during which time it may stay completely buried in the sand.
They cannot breathe underwater. Without sufficient water and humidity, terrestrial hermit crabs will suffocate and die. Before placing your hermit crabs in a tank, you need to ensure that the air within is breathable. I think the crab knows best when he is ready to begin the process and well intentioned owners should trust his instinct and not try to second guess and predict the timing of such a critical, hormonally controlled event such as molting.
When we try to control and oversee aspects of our crabs welfare that is better left to the crab itself, even if done in a well-meaning way, the outcome can be disastrous. Just as a butterfly helped from it's cocoon will not survive. Our responsibility to these creatures in our care is to provide them with what they need to survive. What better way to do that than to provide what they would have if they were living in nature, especially when it works!
Nav Menu 2. Successful Molting Molting has to be the most stressful time in a crab's life so it is critical that hermit crab owners have the correct information. Molting is the process by which a hermit crab grows. It involves shedding of the exoskeleton and for a short time afterward the crab is unable to move until it regains muscle control and the new exoskeleton hardens up. At this point the crab will begin eating the old exoskeleton which helps to recycle calcium and other minerals necessary for the new exoskeletons health and rigidity.
Because hermit crabs are vulnerable during this time, they tend to bury underground shell and all! Prior to burying, the hermit crab will begin to store water and nutrients which can be seen on larger crabs as a gray-black bubble located on the left underside of the crabs abdomen.
The water will be used to expand the exoskeleton during ecdysis and the stored nutrients will sustain the crab while buried. Salt plays an important role in the shedding process.
Hermit crabs need to store salts in addition to water in order to build up hydrostatic pressure necessary to burst open their exoskeleton so that they can pull out of it. Hermit crabs usually begin to show signs that an impending molt is near.
Some of the common signs and symptoms to watch for are as follows: Excessive digging behavior: this will be noticed in crabitats that are not set up properly with a substrate deep enough for the molting crab to bury in i. In nature hermit crabs bury underground to molt. They need extended darkness so that the molting hormone can be secreted and protection from predators and the elements during this vulnerable and critical time.
If crabs are not provided substrate preferably sand or sandy soil that is deep enough and moist enough to completely bury, they may attempt to molt on the surface. Small crabs may be able to accomplish this feat, but the danger lies in the possibility of other crabs scavenging the freshly molted crab who is unable to move until he regains muscle control and hardens up.
A freshly molted crab has an enticing smell to other crabs, who may take advantage of the opportunity for a free meal. Jumbo crabs have an increasingly difficult time molting as they get older. It is difficult for a jumbo to survive a surface molt. Excessive time spent in both the fresh water and salt water dishes: Crabs getting ready to molt need to store an abundance of water that they can use not only for survival, but in order to swell and break open their exoskeletons.
