This colonial animal is comprised of hundreds of tiny zooid animals, each inhabiting one siphon as seen in this picture

These ascidians come in a variety of colours; there are sponges and other colonial animals (bryozoans and gorgonians?) in the shot too. Darwinella australiensis encrusts the ascidians

Nature's amazing underwater garden again! Inside these ascidians is a small animal that siphons and filters water for food; you can see the orange siphon clearly on the basal ascidian down the bottom
