Abstract: Pannychia moseleyi is a deep sea holothurian found at depths from approximately 500 meters to 3000m in the Monterey Bay Canyon. The bioluminescence in Pannychia moseleyii has a complex dynamic pattern spread throughout the epithelium, but absent from the tube feet, papillae, and tentacles. The waves observed were greatly varied, but can fit into three general classifications -- spiral, circular from a point, and travelling. The basis of bioluminescence in Pannychia appears to be intracellular and microscopic, and shows strong evidence for being passed in an excitable medium such as a nerve net. The strongest evidence for the coordination by a nerve net comes from transection studies.
