Hermit crabs can live either on land or in water. They're not true crabs, though. Wonder What's Next? Try It Out Are you ready to learn more about hermit crabs? Find a friend or family member to help you check out the following activities: Ask an adult friend or family member to take you on a field trip to a local pet store that sells hermit crabs.

Do they look like you thought they would? Would you ever want a hermit crab as a pet? Why or why not? If you had a hermit crab as a pet, what would you name it? What kind of shell would you get for it? Pretend you're an inventor who has been hired by a group of hermit crabs to invent a new form of protection.

They're tired of borrowing shells from others. But how else can they protect themselves? Put on your thinking cap and let your imagination run wild. Write a brief description of your proposed hermit crab protection invention and share it with friends and family members. What do they think? Will your new invention work? Are you an introvert or an extrovert?

Introverts tend to keep to themselves and focus inward. Sometimes they are like hermits if they live alone and are socially isolated. Extroverts, on the other hand, focus on others and are very outgoing. Extroverts prefer to be around others most of the time, whereas introverts might rather spend time alone with a good book. Whether we're introverts or extroverts, we all crawl into our own emotional shells from time to time.

Do you remember times when you've put an emotional "shell" of protection around yourself? Try to figure out areas of your life where you might be hiding inside your shell. When you identify such an area, think about how you might be able to come out of your shell just a bit. It may be as simple as trying new things, meeting new people, or making new friends!

KoolKat Sep 8, Sep 9, Anthony Francis Jan 12, I have just recently gotten 2 Hermit crabs I want to get one of those clear shells for it dose anyone know if I am waisting my time? I only have them In a tub I was wondering if you need to filter the water like a fish tank? I found out they are quite clever one of them I left the lid off it and one of them built the sand up right to the top of the Tank.

I think they must get board? Plastic pollution is also a problem for hermit crabs, which often mistake a plastic bottle cap or container for a new home. A study in the Journal of Hazardous Materials found that around , hermit crabs die annually from getting caught in plastic debris on two tropical islands in the South Pacific.

When these trapped crabs die, they release a pheromone signal to other crabs that there may be a shell available, which lures even more crabs into a death trap.

There are many different species which each grow to different sizes under different conditions. The most common crabs in the US, "Purple Pincher" hermit crabs, can grow to be quite large provided that they are able to tunnel underground to molt and can find big enough shells.

Purple Pincher crabs can live for decades and reach the size of a softball huge compared to the young crabs you typically see in stores. My Ecuadorians also preferred shells that were far too small, and also changed shells very infrequently.

They were particularly fond of shells where the spiral inside had been worn or broken away, leaving them more room to squeeze in.

I would try something with a slightly more D-shaped hole. They probably won't be fond of the heavy O shaped Turbo and other sea snail shells.

I would recommend a Crown Conch shell since they are the top choice of my ecs. They are available online, possibly at a local pet store, and I have also seen them frequently in craft stores although the shells at craft stores may been treated with harsh chemicals like bleach, so some people would not recommend buying shells there.

Nice article. I learned a lot from your information. I also have many lovely hermit crabs, I will check your blog later. Also, welcome to my blog. I post many lovely pictures of my hermit crabs there. Tanya, it's difficult to say what would happen with 3 hermit crabs in that tiny of a tank.

Since it would be impossible to provide everything that they need - including fresh and sea water treated to remove chloramines, deep enough substrate for the crabs to bury, controlled humidity, controlled heat, extra properly-sized non-painted shells, climbing and places, a few other crabs, and balanced nutrition - the crabs would be under incredible stress.

Generally 10 gallons or 8 for small crabs is the minimum size tank that can accommodate two or three hermit crabs. Hermit crabs eat their own exoskeletons after moulting to replenish lost nutrients, so if a crab happened to shed its exoskeleton above ground which will not happen if the crabs have a proper habitat , others would certainly enjoy the free meal.

While it would appear that they are eating the crab, it is only the shed exoskeleton. They would not actually eat a crab unless it is a matter of survival. Do hermit crabs go cannibalistic if their living quarters are to small? Anon, that's an interesting question. The shells are created by snails and the coil direction of the snail's shell is predetermined in their genetic code.

Through mutations or hereditary genetics, snails sometimes produce shells with reverse coils. As far as I know, hermit crabs will always choose a shell which coils to the left. Depending on the type of snail, reversals may be so uncommon that reversed creatures cannot find compatible mates, making reversed shells for some species quite rare. Some snails have diverged into entirely separate species due to reversed coils.

It's quite an interesting topic, thanks for asking! Generally a heat source above the crabitat is the most appropriate. If an under tank heater is able to warm the air in the crabitat, either the substrate is too shallow for the crabs to bury, or it is so hot that they may be in danger when buried.

That doesn't mean that it cannot be used as a heat source if set up properly and monitored, but I would not recommend it.

I have used an "under tank heater" on the back wall of my smaller isolation tank which allows it to heat both the sand and the air. If the sand becomes too warm on that side, the crabs can tunnel away from the warmth. My primary tank is heated by a fluorescent day light and red night light, but most of the heat is provided by aquarium heaters in two 5 gallon pools at either end.

The humid heat from the pools keeps the air at the correct temperature and humidity, and the warmth from the water also radiates noticeably about 6 to 8 inches into the sand. A litle off topic, but do land hermit crabs need under tank heater to supply heat or an above tank heater like a heat bulb? Thanks for reading, there are several mentions of not using painted shells but I will add more higher up in the article. Health Problems. Freshwater Pets. Freshwater Aquariums. Saltwater Pets.
