Obviously a different world with different species, what they discovered was incredibly diverse. A world teeming with life! Sessile organisms and pelagic creatures alike find the vent ecosystem more than suitable for "home life".
But how? How can they survive the poisonous water? And what about the tremendous heat?

In the world of science, the primary producers of each ecosystem are the organisms that others rely on for survival. Primary producers translate energy to food for the following consumers in the food chain. In a hydrothermal vent community, chemosynthetic bacteria are the important members, the primary producers. Since plant life is unable to grow and the concept of marine snow hardly provides enough food to account for the oasis, other vent organisms depend on the bacteria to translate the toxic energy into usable energy. Growing in thick mats on the surrounding surfaces near hydrothermal vents, chemosynthetic bacteria is grazed upon by small invertebrates like amphipods and copepods. Larger organisms like eels, crabs, jellyfish and even octopus, feed on these smaller organisms and thus continues the hydrothermal vent food chain of predator and prey.
This ecosystem can never be described as merely managing to survive, but more properly as flourishing. The bacteria provides plentiful energy for the organisms in the community.

Many scientists take advantage of this deep-sea anomaly to expostulate on the theories of our origin, saying life may have begun at these points. But sadly, this is just another useless grasp for those striving to find the reason for life in other places than the true account. No sketchy gaseous explosion or bubbling pot can create the intricacy we are surrounded by. The account in Genesis is much more plausible.
Thank you for reading this weeks installment of the Hydrothermal Vent Series. Be sure to come back soon to find out how these incredible creatures can withstand the heat!
