Summary
These gooseneck (or goose) barnacles were collected from the Hunter Marine Park (formerly Commonwealth Marine Reserve) off NSW at ~2500 metres deep during the 2017 'Sampling the Abyss' voyage. One of their alternative common names - 'goose barnacle' - came from a misconception during the Middle Ages that they may in fact be goose eggs. These barnacles may look like shells, but they are actually more closely related to crabs. They are filter-feeders and will open their plates to extend leg-like cirri to feed from the water column.They are often found attached to other animals or seaweed, presumably to get a 'better perch' for feeding or to aid with dispersal. On this voyage they were seen attached to sea spiders, glass sponge spicules, rocks and even rubbish.
