Hermit Crabs are the most well known crustaceans in the world. They have been around since ancient times and they are still living today. Hermit crabs live all over the world, but their main habitats include coral reefs, rocky shores, sandy beaches and mud flats. Their preferred habitat is in warm waters where there is plenty of food available. Hermit crabs are not very social animals. They tend to stay alone in their own little shells and don’t form colonies like other crustaceans do. However, some species of hermit crabs do live together in groups called “hermit colonies”. These communities consist of several individuals living under one roof and are usually found near coral reefs or rocky shorelines. Hermit crabs have two sets of claws on each foot, which allow them to dig into the sand and burrow themselves underground. They can survive without sunlight for up to six months at a time. When they emerge from their shell, they are able to move about using only their clawed feet. She may spend up to three years inside its shell before it dies out completely. They can grow to be around 4 inches across the ocean, but species that live on the Atlantic coast are around 1.5 inches. They can live for up to 10 years. Hermit crabs are omnivores and primarily eat meats such as dead fish, plankton and brine shrimp. Crabs also scavenge for fruits and vegetables they can find on the sea floor. The crab’s favorite food is the algae that grows on the outside of their shells. Hermit crabs usually bury themselves in sand to protect themselves from predators and harsh weather conditions. Guess what, the hermit crab is also known as a sea robin!
