Physiology and Cell Biology
This chaetognath has a luminescent organ on the ventral edge of each anterior lateral fin. Each luminescent organ contains about 8,000 bioluminescent particles. The particles are packed in hexagonal chambers and covered by a thin layer of tissue. The chaetognath can shed these particles into the water to form a luminescent cloud.
