The organisms living near hydro thermal vents are cold blooded animals whose body temperature does fluctuate as per the environment. There thermo regulatory receptors are missing and they do not posses any control over their body temperatures.
it is a type of chemical that algae force out (I know it sounds disgusting but that's what it says in my book) !
chemical nutrients from Earth's interior

Sulfur.

chemical reactions
Chemosynthetic organisms obtain their energy directly from raw chemicals in their environment. Examples of this include tubeworms living next to hydrothermal vents.
hydrothermal vents are on the bottom of the ocean where there is not much sunlight and is so deep, that they thought it would be impossible for any organisms to survive. apparently, hydrothermal vents provided heat and produced chemicals which bacteria feed on. And other animals feed on bacteria.
chemoautotrophssulfur
Special bacteria (chemosynthetic bacteria) live there which use the sulfur from the hydrothermal vents to make their own food. Other organisms, such as copepods (and other zooplankton), eat this bacteria. Other organisms, such as snails, shrimp, crabs, tube worms, and fish eat the copepods. Therefore, the number of organisms living in these vent systems are 10,000 times greater than areas in the ocean that do not have hydrothermal vents. These life forms would not be possible without the chemosynthetic bacteria, since sulfur is toxic to almost all other forms of life.
Hydrothermal vents are commonly found near volcanically active places, areas where tectonic plates are moving apart, ocean basins, and hotspots. Vent organisms depend on chemosynthetic bacteria for food. The water from the hydrothermal vent is rich in dissolved minerals and supports a large population of chemoautotrophic bacteria.

Bacteria. It uses the process called chemosynthesis to produce glucose.
Shrimp, Giant clams, and Tube worms
such organisms would be bacteria, fungi, protozoa, algae and other microorganisms mostly you would only need to find a rock and have a powerful microscope
