This video shows a time-lapse view of a small patch of muddy seafloor, 4,000 meters (13,123 feet) below the ocean surface, at a deep-sea research site called Station M. Researchers at MBARI have studied the animal communities at Station M for over 30 years. This is a short clip of a longer series of photos that were taken every hour over a few months.
