How to Organize the Shells


Group by geography, type, or size
- Box with glass or plastic lid
- Foam to cushion shells

Basic information to include with shell:
•Common and scientific name
•Date
•Place

How to Identify the Shells

How to Clean the Shells

  • Rinse in water and let dry away from sun
  • “Soak in 50/50 bleach and water for a few hours”

What & How to Collect


Take only specimens without animals inside.

  • Bring containers – bag, covered jar, or bucket
  • Take shovel or digging tool, sieve or framed mesh sorter
  • Take pencil and plastic-covered note pad
  • Return rocks and other habitats to their original position if moved to find shells

What to Wear When Collecting


  • Take a jacket and hat during non-summer months
  • Wear waterproof, non-skid shoes (NOTE: old sneakers will do)
  • Use sunscreen and hat in spring and summer

Where Do I Look for Shells?

  • Rock tide pools
  • Sandbars
  • Tidal flats
  • Seaweed
  • Piers
  • Driftlines

Why Is the Shell Empty?

  • Red tides from nitrates and phosphates
  • Invasive non-native species
  • Predators may:
    - Bore holds and take contents
    - Pry open contents
    - Swallow whole and then discard shell later

What Time is Best for Shelling?


Go during low tide for the greatest expanse of beach and shells - check weather reports for low tide times.

Go after a storm - cold fronts can push water away from the beach, somewhat like a low tide and tropical storms can churn up the water to bring shells ashore.

Where Is the Best Shelling?
