Bladderwrack

Fucus vesiculosus
The seaweed called the kelp is a very common sight along many areas of the seashore in the New England area and the Eastern seaboard of the American continent, it is also called the bladderwrack because of the bladder like pneumatic floats attached to the branches – it is found predominantly in the rocky beaches and areas which have some well defined low tide water marks on the shoreline. The kelp is seaweed, and has an olive green coloration, it is also spread out in regular branches, with each of the branches characterized by a peculiar spiraling shape, and the seaweed has a leathery feel and is slippery to the touch. Like most underwater sea weeds, the kelp has paired bladders, though some of the branches may sometimes be without any air bladders – these pneumatic structures keep the kelp floating in the tossing waters of the sea shore.
