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 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?

Bella Apr 23, Amid the chaos, males and females find each other, coming partly out of their shells so the male can transfer a sperm packet to the female, which fertilizes her eggs. The larval crabs will live on ocean plankton, molting through several stages before acquiring a shell of their own and coming back to land. 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.

Fighting Fighting can be an issue if your aquarium is over populated and crowed. You might need to get a larger aquarium if too many crabs live together, and add more climbing ornaments to space the crabs out. Some hermit crabs might get aggressive and pull other crabs out of their shells to steal. It is important to have enough spare shells to avoid this happening. Health Common health problems with hermit crabs include stress and poisoning, so make sure you keep a close eye on them.

Signs of stress include inactiveness, sluggish, and leaving their shells. Stress can be caused from overcrowding and bullying, living alone, being dropped on their shells, or extreme temperatures either too hot, or too cold. Hermit crabs can be easily poisoned from cleaning sprays and detergents used around the house, and only a small amount can be fatal. Make sure no chemicals are used when cleaning the aquarium, and none are used near your hermit crabs including hairspray and air fresheners.
