Seaweed, also known as algae or Algues, is a fascinating and diverse marine plant that can be found in various forms and locations around the world. From pressed seaweed specimens like C016 / 6127 to dense growths of Bootlace seaweed in Kimmeridge, Dorset, England, this versatile plant never fails to captivate us. One remarkable sight is the low spring tide on Bristol Channel at Lundy UK. Here, the exposed rocks are adorned with vibrant seaweed species, creating a stunning display of colors and textures. Similarly, Donaghadee Harbour in County Down, Ulster showcases the beauty against the backdrop of Northern Ireland's picturesque coastline. In Berneray's East Beach located in North Uist, Outer Hebrides of Scotland lies another breathtaking scene where seaweed blankets the shorelines. This natural phenomenon adds an ethereal touch to this already idyllic location. Seaweed not only enhances our visual experiences but also plays a vital role in ecosystems worldwide. The Weedy seadragon male carrying eggs through a kelp forest exemplifies how these plants provide shelter and protection for various marine creatures. The historical significance cannot be overlooked either. During World War I (WW1), cartoon depictions often featured mermaids swimming amidst U-boats surrounded by vast stretches of underwater vegetation like seaweed. Even centuries ago, people recognized the allure of these oceanic plants as depicted in an aquarium chromolithograph from 1895 or captured on postcards such as Rye Beach Postcard from New Hampshire dating back to 1903. From Porth Neigwl's Hells Mouth on Llyn Peninsula in Gwynedd Wales to California's kelp beds where sea otters find solace among swaying fronds - each location tells its own story about the importance and beauty across different continents.
