As children we always referred to bull kelp as sea onions as the floats look like onions. I still call them sea onions and still enjoy jumping on them to pop the floats.

Bull kelp grows entirely in one season, from spring to fall. It can grow up to 2 feet per day, up to a length of 80 ft. The float at the end of the kelp is filled with up to 10% carbon monoxide gas.

Bull kelp has many names including; bull whip kelp, ribbon kelp, giant kelp, horsetail kelp and sea otter’s cabbage. I call them sea onions…
