Hydrothermal vents are an unlikely environment for animals to flourish, characterized by rapid changes in temperature and a challenging chemistry: acidic pH, rich in sulfur and methane. Not to mention the high hydrostatic pressure and the darkness of the deep sea.

Deep-sea hydrothermal vents are hot springs on the ocean floor. Sea water penetrates into the ocean crust, becomes heated, and rises to the seafloor surface carrying dissolved nutrients. Around these vents, far from any sunlight, vibrant biological communities are found. Here, microbes play the role of primary producers through chemosynthesis—similar to the role that plants play on land through photosynthesis.
