The Crabbiest Quiz On Earth

The land hermit crab needs those shells to cover and protect its soft and vulnerable abdomen. The exoskeleton of the land hermit crab does not cover its entire body, so it relies on finding and using abandoned shells as a protective covering.

A hermit crab should be housed in a huge tank with lots of sand or other substrate, as well as things to climb on. This is because hermit crabs are terrestrial creatures and require a spacious environment to move around and explore. The sand or substrate provides a comfortable surface for them to burrow and molt. The proper lid is necessary to maintain the heat and humidity levels that are essential for their survival.

The ideal heat and humidity for a hermit crab tank is around 80 degrees (F) and 80 percent.

Hermit crabs are known for their digging and tunneling behavior. They enjoy digging up the tank decorations and tipping over their dishes, which suggests that they love to spend their days engaging in these activities.

The correct answer for the type of food a crab should be provided with is fresh organic fruits, veggies, and meat. Even some dehydrated foods of the same organic nature. This is because crabs are omnivores and require a varied diet that includes both plant and animal matter. Fresh organic fruits and vegetables provide essential vitamins and minerals, while meat offers necessary protein. Dehydrated foods can be a convenient option to supplement their diet.

The correct answer is "Aquarium grade salt sold in petstores" because it is specifically designed for use in saltwater aquariums. Regular table salt or sea salt may contain additives or impurities that could be harmful to the fish. The salt substitute for reducing blood pressure is not suitable for use in a fish tank.

The correct answer suggests that hermit crabs should be offered water that is either treated with a dechlorinating treatment or is bottled. It also mentions the importance of providing them with water that has salt in it. This is because hermit crabs require both freshwater and saltwater to maintain their health and hydration.

When a hermit crab is about to molt, it often goes into a trance-like state after burying itself in the sand or any available substrate. During this time, the hermit crab sheds its exoskeleton and consumes it. After molting, the hermit crab resumes its normal activities and starts moving again.

The land hermit crab has modified stiffened gills that enable it to breathe air in a humid environment. This adaptation allows the crab to live on land and obtain the oxygen it needs to survive.

The correct answer is ten, counting the little ones it uses to keep from falling out of its shell. This is because a land hermit crab has eight legs for walking and two specialized legs called "pereopods" that it uses to hold onto its shell and prevent it from falling out.

The correct answer suggests that the substrate in a hermit crab's tank should be at a depth that is three or four times the height of the largest crab. This is important because hermit crabs require a suitable environment to molt and burrow. Having enough substrate allows them to dig and create hiding places, which helps in regulating their body temperature and reducing stress. It also provides them with a sense of security and promotes natural behaviors.

All of the above species mentioned in the options - Perlecens, Spinosis, Brevimanus, and Clypeatus - are land species of hermit crabs.

Hermit crabs are most closely related to shrimps, lobsters, and crayfish in the animal kingdom. This is because they all belong to the same taxonomic order, Decapoda, which includes crustaceans with ten legs. These animals share similar characteristics and evolutionary history, making them closely related within the animal kingdom.
