Inside the Nerve-Racking Dive to an Active Submarine Volcano

The chief pilot of a deep-sea submersible recounts exploring Loihi, which will become Hawaii’s next island.

.@SymbiosisRox looking at bacterial #symbionts in the gill tissues of #HydrothermalVent #molluscs (across 6 sites) - these seemed to be structured with respect to vent site, and differences in gene content suggest local adaptation (e.g. to hydrogen concentration) #EESSymbiosis

Unlike Sasquatch and the Himalayan Yeti, the marine yeti is a blonde. The yeti crab never sees the light of day--It lives in an ecosystem disconnected from the photosynthetic world above. The setose chelipeds are covered with filamentous bacteria, which it eats (it is not clear if this is its sole diet, or just a component). It sort of 'farms' these chemosynthetic bacteria on its body to eat. A human farmer who did that would have trouble selling their harvest. . .
