sea otter

There's a rallying cry at various bays and beaches up and down the West Coast; it's "Help the kelp!" The towering brown seaweed with the floating bulb on top is in steep decline. That's alarming because underwater kelp forests provide shelter and food for a wide variety of sea life. The crew now answering the call runs the gamut from seaweed farmers to hammer-wielding scuba divers and might some day include sea otters and octopuses.
