Periwinkle Snails

Taylor McElwain Per.1

Habitat

Periwinkle snails live in tide pools, which are completely under water during high tide, but remain pockets of seawater during low tide.

Daily Changes

- Desiccation

-Temperature Changes

-Salinity Change

-Wave Action and tides (being carried away from tide pool)

Special body adaptations such as, clamming up in the shell, help the snail survive.

Other Problems:

-When snails clam up, there becomes limited oxygen. There is also limited space in the tide pools, which could affect the diet of the snails due to competition for food among other creatures.


How do they move?

Periwinkle Snails move by gliding an contracting muscles.

How does it eat? What Does it eat? What are the predators?

The snails have a radula, which look like a tiny tongue. They contain tiny rows of teeth. Because these particular type of snails are herbivores, they only eat plants. They feed off algae and other sea plants. They fall prey to seagulls, shrimp, fish, and crabs.

Did you know?!

Periwinkle snails are full in nutrients and high in protein. They are delicacies served in restaurants in England and in China.
