The recent appearance of 'stunningly beautiful' blue sea creatures, known as by-the-wind sailors, on Welsh beaches has captivated locals and nature enthusiasts alike. These hydrozoans, with their sail-like structures, have been spotted across Anglesey, Gwynedd, and Tenby, sparking curiosity and awe. One such encounter left a woman, Maxine Allinson, in awe, describing the creature as 'like a crystal'.
As a marine specialist, Frankie Hobro from Anglesey Sea Zoo, notes, these creatures are often mistaken for Portuguese man o' war, but they are smaller, brighter blue, and generally harmless. Their beauty lies in their sail-like structures, which catch the wind and move them across the ocean surface, creating a sparkling effect when sunlight hits them. Hobro also highlights the importance of not touching them due to their stinging cells, which can cause discomfort even when the creatures appear dead on the shore.
The term 'by-the-wind sailors' is fitting, as these creatures are often carried long distances by ocean currents, appearing in autumn and winter. Their small size, about 7cm long, makes them unable to move themselves, and they are often 'dumped' ashore after storms or changes in currents. Large groups of these creatures strand together because they travel in the same currents and are deposited along coastlines simultaneously.
Despite their beauty, it's crucial to approach these creatures with caution. While their sting is generally considered mild, it can still cause discomfort if touched on sensitive areas like the lips or face. Hobro advises admiring them from a distance, ensuring that their beauty is appreciated without causing harm.
The appearance of these by-the-wind sailors on Welsh beaches serves as a reminder of the wonders of nature and the importance of responsible observation. As these creatures wash up, they offer a unique opportunity to appreciate the beauty of the ocean without causing harm to these fascinating marine life forms.
