Hermit crabs are related to anemones. Generally, one or two anemones will be found in the shell of hermit crabs, especially when facing natural enemies, the stinging cells of anemones can provide protection, and hermit crabs can expand the feeding range of anemones. Let's take a look at this website!

What is the relationship between hermit crab and anemone? Because the shell of hermit crab is very beneficial to the survival of benthic organisms, hermit crabs often live with other organisms, such as hydra, shrimp and fish, among which anemones are the most common. However, without natural enemies for a long time, hermit crabs will lose interest in carrying anemones and throw them away.

Although anemones look like plants, they are actually carnivores, and their overall shape is like flowers, which can provide some camouflage for hermit crabs. Anemones also have dozens of tentacles with poisonous stinging cells, which can kill natural enemies for hermit crabs. So when hermit crabs put on new shells, anemones will also take the initiative to move over.

Anemones can only move slowly because they have no bones, so they are easily covered by gravel and their own excrement, so they need a hard layer and flowing living water, which hermit crabs can provide. The feeding range of anemones has also expanded a lot in an instant. You can also get some food residues when hermit crabs are foraging, so it can be said that hermit crabs and anemones are mutually beneficial.

Who is a born hermit crab? Hermit crabs are related to many animals with stinging cells. For example, the above hydra parasitizes on the shell of hermit crab, which can effectively prevent a large number of harmful organisms from attaching to the shell and protect the health of hermit crab. Hermit crabs can not only distribute food residues to hydrozoa, but also significantly promote the sexual development of hydrozoa.

Moreover, hermit crabs sometimes accompany their companions, usually a male and a female, to defend their living territory and even fight to the death with the enemy. In addition, anemones are like a fighting resource, and powerful hermit crabs will seize anemones from the shells of other hermit crabs. And anemones actually give birth to small fish and shrimp. Generally, there are 3-7 shrimps in anemones fixed on the sea floor, and sometimes there are even more than a dozen.

The relationship between anemones and hermit crabs is the result of adaptation to nature, just like why freshwater fish can't be in the sea, and the environment determines their lifestyle.
