Hermit Crabs as Crustaceans

Hermit crabs are crustaceans because of their anatomical and physical similarities to snakes, lizards, and other reptiles. They have a transparent exoskeleton that they can shed to protect themselves from predators, similar in structure to that of turtles.

Aquarium Needs

Arthropods, like hermit crabs, need plenty of space to live and swim around. A standard aquarium size for an arthropod is at least 20 gallons, but it’s best to go bigger if possible. In addition, hermit crabs require a sandy substrate – they won’t do well on rocks or coral reefs. Hermit crabs also love humidity levels above 70%, so ensure your tank has a good humidifier installed.


A hermit crab’s diet consists of a diverse range of wet and dry foods. For example, algae, insects, and worms make up wet foods, while vegetables and fruits make up dry food options. Make sure your hermit crab has access to various food essential for their overall health and well-being.

Moreover, hermit crabs can live a long time with a healthy diet and plenty of exercises. Some hermit crabs have been known to live for up to 15 years! So if you’re looking for an exciting pet that will stay around for a while, consider getting a hermit crab!

Predators and Threats

Hermit crabs are crabs that live in shells that they bring along with them when they leave their homes. These crabs are sensitive to environmental changes, so they must be aware of crab predators and threats that could affect them. Some crab predators that can eat hermit crabs include the common crab, the American lobster, and the tiger crab. 

Another threat to hermit crabs is overcrowding, which can cause them to lose their shells and become vulnerable to other predators and dangers. Keeping your home clean and debris-free is one way to protect these delicate creatures.
