the periwinkle snail eats the algae that grows on the cord grass.the periwinkle snail also uses the cord grass as a place to hide from predators.
It eats decayed cordgrass.
In the UK we call them Winkles, periwinkles and whelks
- The Marsh Crab uses cordgrass as a source of food. - The Periwinkle Snail eats the algae on the cordgrass and it uses it as a place to hide from predators. - The Seaside Sparrows use the cordgrass to make nests.
What I know of that is hermit crabs will eat snails. However, hermit crabs will often use an empty shell of a sea snail.
Snail shells are formed biologically as the snail grows up. Hermit crabs occupy empty shells and other containers, instead.
If you are considering putting periwinkles into your saltwater reef tank, don't. Though they are of no danger to your inhabitants, periwinkles are cold water snails. Yes, they can live in 82 degree tide pools for limited amounts of time, but they will NOT survive more than 3 months in your aquarium. Periwinkles are typically bought in bulk online and I'm sure you can imagine what happens to your marine ecosystem when 50-100 snails die within a week of each other.
A hermit crab and a snail have a symbiotic relationship where the hermit crab uses the empty shell of the snail as its protective home. The hermit crab benefits from the shelter provided by the snail's abandoned shell, while the snail is unaffected by this interaction as it has already vacated the shell. This relationship is an example of commensalism, where one organism benefits while the other is neither harmed nor helped.
Periwinkle snails are small marine snails that are typically found in coastal regions. They have a conical shell and feed on algae and other plant matter. Periwinkles play a role in the ecosystem by serving as food for various predators and helping to control algae growth.
The relationship between a snail and an elodea plant is typically one of herbivory. Snails may feed on elodea, which is a type of aquatic plant, particularly if it is growing in a freshwater environment. This feeding can help control the growth of the elodea, while the snails benefit from the nutrients provided by the plant. Additionally, elodea can provide shelter and habitat for snails, contributing to a balanced ecosystem.
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
They are differnet colours
Many species of ducks will eat snails. In fact, some species are adapted to seek out and eat predominantly such aquatic creatures as snails.
