The Midnight Zone

There are 3 zones in the ocean.The topmost layer is the sunlight zone. In the middle,there is the twilight zone.The last zone is the midnight zone.In this blog, I am going to tell you about the the midnight zone.

The midnight zone has the least life in all 3 zones.An example of life is the  recently-discovered Yeti Crab.They have hair that helps them catch bacteria.This is how one looks like:



The yeti crabs' sientific name is Kiwa hirsuta.It is a crustacean.This species was discovered in 2005 by a group organized by Robert Vrijenhoek of the Monterey Bay Aquarium Research Institute in Monterey, California and Michel Segonzac of the Ifremer and a Census of Marine Life scientist using the submarine DSV Alvin, operating from RV Atlantis.The discovory though, was annouced in 2006.

Another form of life are Giant Tubeworms.Their scientific name is rifta pachpiutila.They are not anelids like leeches and earthworms,but they are a type of mollusk.Here is how some looks like:

The next organisim is bacteria.They start the food chain.They eat chemicals from black smokers.A black smoker is a volcano that has black lava and smoke due to the black minerals going through sea vents.I am positive there are more creatures out there.The only problem is it is not easy getting down there. This is due to water pressure.When you go down to the midnight zone, it feels like you have a schoolbus on your head!This is all I have to say about the midnight zone.
