These creatures are small, free-floating hydrozoans found on the surface of the ocean. The valella has a distinctive oval-shaped, flat and translucent blue body called a float or pneumatophere. They also have a small rigid sail-like structure that protrudes from their body and helps them catch wind and move across the surface of the water. The sail is typically triangular or semi-circular and oriented diagonally. Their color is usually deep blue to a purplish-blue color, making them quite striking against the backdrop of the ocean. Lastly, a Velella also has tentacles, hanging below the float, which are short and dark blue in color. The tentacles are used to capture plankton and other small prey. Although they contain stinging cells, they are generally harmless to humans. The velella are often found in large numbers, sometimes washing up on beaches in significant quantities, creating a spectacular sight. They provide a fascinating example of how marine life adapts to wind and ocean currents for movement and survival.
Seeing a velella for the first time evoked a range of emotions and reactions since it was my first time seeing something like this. I felt inspired to learn more about them. I mostly wanted to know was why they were there and the reason why there where so many of them lying on the shoreline. Plus, I was really surprised by their beautiful blue color. I also felt some concern upon seeing them for the first time, since I did not know if they were harmless to humans or not. I also wondered if they were supposed to be on the shoreline or if there was something wrong that had caused them to be washed up.
