The Vent Garden is a stationary leviathan that anchors itself above thermal vents and houses aquatic flora inside its bell-shaped interior.
Anchoring Tentacles: Six tentacles anchor the Vent Garden to the seafloor around vents. Each tentacle is capped by a set of thick curved hooks that grow downwards, keeping the Vent Garden firmly in place.
Transparent bell: The hollow bell of the Vent Garden has a narrow opening large enough to accommodate human entry. The Vent Garden feeds on thermophilic bacteria and other microorganisms that spew from the vent below. The top of the bell also has an opening that continuously releases water to maintain a consistent internal pressure.
Symbiotic relationship: The bell houses six branching platforms that resemble coral. These platforms contain aquatic flora that remain safe from foraging herbivorous fish. In turn, the flora absorb and synthesize some of the heavy metals and gases emitted by the vents below.
Assessment: Docile, nutrient rich, harbors flora.
