Communities on Sandy Beach Shores
* Sandy Beach Intertidal Zone
• No stable, fixed surface
• Burrowing provides more stable environment
• Less risk of temperature extremes and drying out
Burrowing invertebrates include: Mollusks (with a soft body, hard shell—most, not all)
(clams and mussels most common); Worms (annelids) and Sand Crabs.
