However, the hermit crab will most of the time retreat back into its shell to protect itself instead of fighting. If the thing attacking it is small enough, the hermit crab might fight back. This is a symbol of knowing when to fight.
The hermit crabs also convey another important message to the employees those who prefer to remain in the same corporate. For shell change, the hermit crabs follow ‘vacancy chains’. The biggest crab when it shifts to the next one, its shell become empty and the next in the order would occupy it.
Can Hermit Crabs Recognize Their Owners? Hermit crabs have good memories. As per Ethology, hermit crabs will remember their tankmates and the social hierarchy within the habitat, which suggests the same will apply to human owners. Hermit crabs won’t recognize humans by sight.

Experiments in bees, crabs, and octopuses show that some invertebrate animals can learn from painful experiences, have positive and negative emotion-like states, and might even experience a range of other emotions beyond pain and pleasure.
With the right care, your hermit crab can live up to approximately 15 years. Hermit crabs love company, so have multiple crabs living together. They’ll become more active with the company. Hermit crabs are nocturnal and will sleep throughout most of the day.
Hermit crabs communicate by chirping. Their soft high pitch chirps sound like a small frog. Chirping can mean a territorial dispute or that the crab was startled.
Hermit crabs are known to form groups, or ‘clusters’, which may occur at sites of high shell availability. Clustering may also have anti-predator benefits, if individuals in larger clusters able to spend less time engaging in defensive behaviours such as hiding in their shells.
Hermits are not aggressive and they do not bite, but they will reach out and try and hold on with their pincher claw. They usually are passive, if they are held incorrectly they will grab your skin to hold on.
They learn to associate handling with the reward of food and an amazing amount of trust is the end result. I highly encourage my customers to try hand feeding. It’s a great way to bond with your hermit crab! Unfortunately as a hermit crab owner, it’s just a matter of time…you will get pinched.
Hermit crabs pick their shells based on preference and can determine which shells will best meet their needs. So, hermit crabs are intelligent, it seems, but only within their own metric. Their minds have evolved sufficiently to meet their day-to-day survival requirements.
It is perfectly fine for you to hold your hermit crabs. However you have to respect the crabs’ ability to pinch. They are in fact CRABS and most people associate crabs with claws. The key thing to remember when you are holding your hermit crabs is to not take your eyes off of them.
Happy, healthy hermit crabs will be curious and active, especially after dark. They’ll roam their aquariums, sporting vibrant colors and bright eyes. They’ll be docile and have 10 intact limbs. If your hermit crabs are sluggish and lethargic, pale, aggressive, or spend prolonged periods hiding, they’re likely unwell.
Any size hermit crab can be cooked and eaten, but small hermit crabs do not have much meat on them, so it may not be worth shelling it to eat. It is best to cook larger hermit crab that are at least 4-inches wide, to get a decent amount of meat.
Fresh water is needed for drinking, and most hermit crabs will also drink salt water (some also like to bathe in the salt water so providing a dish of salt water big enough for the crab to get into is a good idea).
In less dire circumstances, hermit crabs associate being jostled around with being tossed by strong winds or heavy currents from the ocean. They may even get jumped by other hermit crabs for their shell. For this reason, even if you have good intentions, you should not immediately snatch up a hermit crab to snuggle.
The nervous system of a crab differs from that of vertebrates (mammals, birds, fish, etc.) in that it has a dorsal ganglion (brain) and a ventral ganglion. The two nervous centers are connected by a circumesophageal ganglion, i.e., it circles the esophagus.
Hermit crabs generally like to play without much human assistance; but when they have the right toys, they couldn’t be happier. A well-stocked aquarium is all your hermit crab needs to play, so give him a combination of things he can climb on, through and under.
Hermit crabs thrive at humidity levels between 70% and 80%. Mist their terrarium with non-chlorinated water as necessary and use a hygrometer to keep track. Put a fluorescent or LED bulb in the terrarium hood to light the habitat for 8 to 12 hours a day. Do not use high-output UVB lighting for hermit crabs.
Hermit Crab Feeding
Fresh fruits and vegetables such as apple, carrot, kale and banana should be offered 2-3 times per week. Hermit crabs will also readily accept dead insects such as dried mealworms, and crickets which can be coated with a calcium and vitamin supplement.
Hermit crabs need companionship, plenty of climbing room, substrate to bury themselves in for molting, humidity, warm temperatures, extra shells, fresh and salt water (dechlorinated aquarium salt only), and much, much more! Never release a captive crab back into the wild. Take Action for Hermit Crabs!
Yes your hermits do talk. They make a croaking or cricket kind of a sound. Usually they make this noise at night but if you move them around when they do not want to be disturbed, they will croak at you saying leave me alone.
They’re nocturnal, sleeping at night to avoid the sun. Hermit crabs remain in their shells while awake, only growing active when night has fallen. All hermit crabs emerge from their shells at some stage, as no hermit crab sleeps all day. It may be molting if you haven’t seen a hermit crab in a while.
Hermit crabs are believed to stridulate when afraid. A loud, squawking chirp is an expression of fright. Hermit crabs can fight over shells, but not all are prepared to fight. For example, a smaller hermit crab may be frightened by the aggressive behavior of a larger rival.
Stridulation is the act of producing sound by rubbing certain body parts together, such as insects do when they rub their legs. Scientists have known that crabs use this same leg-rubbing technique to communicate, as well as specialized ridges on the claws and arms that are rubbed together to produce noise.
