This is the zone where the action is — biologically speaking. Here the water is shallow enough for light to reach the bottom making it ideal habitat for eelgrass and many types of marine algae or seaweeds.
These plants provide food and shelter to a myriad of small creatures ranging from prawns and crabs to small fish. The sand and mud bottom is also ideal habitat for burrowing creatures such as clams, sandworms and ghost shrimp.
This abundance of “small fry” attracts larger predators such as adult salmon, marine birds, seals, and sea lions. Occasionally Biggs killer whales cruise the shallows looking for unwary seals for dinner.
