On a seamount near Macquarie Ridge lies a city several kilometers down. No mermaids, merman, or Snorkels reside here. Rather millions of brittlestars, living arm tip to arm tip, extend there tiny arms toward the surface to capture food. Much like a large city arises near a river, sheltered harbor, or gambling, Brittlestar City thrives because the Antarctic Circumpolar Current passes over the seamount at a brisk 2 knots. This makes it prime habitat for organisms who make a living filtering particles out the water. You can see more photos and video here.
