![]() ![]() Whatever their size, violet shells on any beach give me a fine marine animal fix. ![]() On the same beach, I also found the biggest Portuguese man-of-war I’ve ever seen. The snails might be different species, or the big ones might have grown large due to these nutrient-rich waters. I’ve often found violet snail shells on Hawaii’s windward beaches, and could fit about 10 in my palm. When they mature, the tiny snails build their own bubble rafts and continue the nomadic existence. When the sperm hit their target, the female lays eggs and carries them with her beneath her bubble raft.Įggs hatch into a drifting underwater form. As a result, when a male violet snail senses a female in the area - they can’t see each other because violet snails have no eyes - he ejects sperm in her general direction. When an animal can’t control its course, it’s tough for the sexes to get together. Violet snails shells are left behind by animals that survive by eating Portuguese men. Portuguese men-of-war are violet snails’ main food. Violet snails build their own bubble rafts and float away. Unlike us, violet snails don’t get a sting when they bump into blue bottle tentacles. That’s why during strong onshore winds, we find both species stranded on beaches. Throughout the world’s tropical oceans, violet snails and other members of their drifting community, including Portuguese men-of-war (called blue bottles here in Australia), are at the mercy of winds and currents. To lose the raft is to sink to the bottom and drown. That survive by eating Portuguese men-of-war. Violet snails shells are left behind by animals In either case, the creature secretes mucus from its foot to coat its bubbles, creating a rubbery raft. Another theory is that the snail blows bubbles from air it has taken into its shell. Some believe that the snail agitates water with its foot to make bubbles. Healthy ones float offshore, upside down, on self-made bubble rafts. The exquisite shells, lavender above and purple below, lay 50 or so feet above the high tide line, suggesting that storm winds drove the snails toward shore and high waves spit them out. The long-dead animals I found stranded on this 2-mile-long sand beach, suitable for small plane landings, are the largest violet snail shells I’ve ever seen, nearly 2 inches long and an inch high. Sure, marine animals lying on beaches are dead or dying, but that means I can pick them up or turn them over and admire to my heart’s content. Violet Sea Snails can travel hundred of miles floating on sea currents.AIRCRAFT BEACH, EURIMBA NATIONAL PARK, Australia » For me, beach walking is often as rewarding as snorkeling. As soon as the young snails hatch out, they make their own rafts of bubbles to keep afloat. If you pick this snail up from the beach, you could well get purple dye on your fingers.įemale Violet Sea Snails make bubble mucous rafts to lay their eggs on and after they have laid the eggs, the females release the rafts into the open sea. The shell is a violet and a pale purple colour and its body is also a violet colour. It has about five spirals on the shell which are also known as ‘whorls’. paper thin shell that is around three centimetres in diameter. To keep afloat it creates a raft of bubbles from its own mucus and then hangs head down from the mucus so it can feed. This snail is quite unusual because it spends most of its life floating on the surface of the open sea. However, sometimes after strong storms it may be found washed up on shores in the west and south-west of England. The Violet Sea Snail is a small ‘pelagic’ snail which means that it lives in the open sea away from the seabed and away from shores. ![]()
