The 640-meter depth recorded for Bathysphaera is near the boundary of which two ocean zones?
Answer
Mesopelagic and bathypelagic zones
The depth reported for the 1932 observation of the *Bathysphaera*—640 meters—places the creature precisely at a significant ecological transition point in the ocean column. This depth sits at or very near the boundary separating the mesopelagic zone, also known as the twilight zone where some downwelling light still penetrates, and the bathypelagic zone, commonly called the midnight zone, which is characterized by absolute darkness. This transitional habitat suggests that if the sighting was accurate, the giant fish might employ different visual or bioluminescent strategies compared to creatures living exclusively in the deeper, lightless regions.
