This would generally be viewed as a symbiotic or mutual relationship. The anemone benefits by being transported to different locations, some of which may be richer in food supply. The crab benefits from the camouflage the anemone provides, the partial protection of having a stinging anemone in close proximity and also from pieces of food which the anemone may drop.
Commensalism
A shell provides protection and shelter for a hermit crab, which uses it as its home. The hermit crab carries the shell on its back and can move to a larger one as it grows. This symbiotic relationship benefits both the hermit crab and the shell.
Snail shells are formed biologically as the snail grows up. Hermit crabs occupy empty shells and other containers, instead.
What I know of that is hermit crabs will eat snails. However, hermit crabs will often use an empty shell of a sea snail.
Hermit crabs are known to use empty snail shells as protection for their soft abdomens. They often inhabit shells left behind by snails, creating a symbiotic relationship where the hermit crab benefits from the snail shell and the snail is not negatively impacted.
well mostly the difference between crabs and hermit crabs is that one is not born with a shell and one is. Also hermit crabs tend to be smaller
the hermit crab attaches the anemone to its shell as protection from the big fish with the sharp teeth and octopuses and squids and you know what else is a hermitcrab YOUR MOTHERR:P
When a sea snail dies, its shell eventually washes up on shore, where the hermit crab uses it as its new home. Therefore this would be commensalism, however since the snail already died there is no living symbiosis.
It depends who the Hermit Crab borrowed its shell from.
Yes, the snail benefits from the hermit crab's actions in a mutualistic relationship. When a hermit crab uses a shell, it can create a more stable environment and protection for the snail if it moves into the abandoned shell. Additionally, the hermit crab's movement can help the snail access new food sources and habitats. Overall, the relationship can enhance the survival and well-being of both species.
Though often described as parasites, the relationship is an example of obligate commensalism, as the barnacles neither harm, nor benefit, their host.
When a hermit crab outgrows its shell, it will move into a larger shell.
