A Seashore Walk

Rough periwinkles sit on a bed of barnacles.
Limpets leave a zigzag trail on rocks as they move along scraping off algae and seaweed with their strong teeth.
A painted top shell sits in the water of low tide.
A chiton displays its overlapping protective plates running down the back.
Blue mussels use byssus threads (which you can see on the right, in front of the barnacle shell) to attach to rocks and sometimes to stop a predator from making them a meal.
A blue-rayed limpet nestled inside a hole chewed on a piece of kelp.
Students from Helen Scales' class visit the seashore to explore mollusks.
