Eight hundred metres below sea level, a living fossil lurks. The chambered nautilus is an ancient relative of the squid and the octopus. It migrates upwards from these depths every night to feed on the tiny shrimp by the Great Barrier Reef wall, returning back to the darkness during the day. This clip shows the first images of a baby chambered nautilus, no bigger than a two pound coin, as it propels itself forward by squirting water.
