A diver found an ‘alien slinky-like’ squid egg - as long as a human leg.<br /><br />Andrea Nemeth was diving off Norman Reef, Queensland, Australia, on January 12 when she spotted the ghostly figure floating about 10m underwater.<br /><br />Creepy footage shows the one-metre-long Diamond back squid egg mass being buffeted by the current.<br /><br />Getting a closer look, the 23-year-old was able to show the inside ridges of the structure that made it look like the classic children’s toy, a slinky.<br /><br />Andrea, originally from Austria, said: “At first I felt like I had just encountered an alien. It was such a dark and gloomy day in the water and this thing just appeared in front of me, spiralling in the current.<br /><br />“I'd never seen anything like it before. I only found out later it's a Diamond back squid egg mass.<br /><br />“I was working as an underwater photographer and dive instructor on one of the day boats in Cairns.<br /><br />“I first spotted it drifting at around 10m depth. It quickly got taken by the current to about 15m and that was the last time I saw it.<br /><br />“It was a bit longer than a metre in length and around 15-20cm in diameter. I'd compare it to the size of an adult’s leg.<br /><br />“I have been diving since I was 11 years old, I used to dive in freshwater lakes back home. My dad introduced me to diving and it has been my passion ever since.”
