The Upper Shore The upper shore is under water only a few hours each day. Conditions vary from hot summer days to freshwater rainfalls to winter ice. All the creatures here have some structure or behavior to prevent themselves and their young from drying up.

Barnacles

Feeding Barnacle

Sand Flea

The Middle Shore This zone is covered by seawater 1/2 the time. Plants and animals have more water time to feed and breed. Motile animals travel about during high tide with lots of time to find shelter. Ropy brown rockweeds drape the rocks at low tide, but during high tide their air bladders let them float.

Fucus (Rockweed)

Ascophylum nodosum

Green Crab

Amphipod

Smooth Periwinkle

Rough Periwinkle

Blue Mussel

Dogwhelks

The Lower Shore This zone is covered by sea water except during low tide. This is the kelp zone with lots of brown kelp. Watch for adaptations of shape and behavior that helps plants and animals to hang on while pounded by crashing surf.
