Metafilter is walking from San Francisco to Tokyo!
We have walked for 212.5 hours and are 637.4 miles into our 5141.6 mile journey.
Of note today:
Ocean depth at our current location is ~3400m:
The bathypelagic zone is from 1,000-4,000m, and sunlight does not penetrate the eternal darkness.
Popular sources sometimes refer to this as the midnight zone. The only light available at these depths is generated by
bioluminescent organisms, some of the strangest marine creatures of the deep.
Plants are non-existent in the bathypelagic zone. Animals that can live here survive on the dead material,
or detrius, that falls from surface zones on other animals that live in the deep sea.
About five percent of the primary production from the surface makes it to the bottom of the ocean. Less food means lower biomass.
Occasionally, large items like dead sharks or whales reach the seafloor, but generally food is scarce.
The giant squid is a resident of the bathypelagic zone and serve as a food source for deep-diving sperm whales.
