👉 Hydromedusae are a group of organisms that make up the hydrothermal vent system, which is a complex network of hot, liquid water and gases known as hydrothermal vents. These vents are found on the surface of the Earth's crust at high temperatures and pressures, where the resulting steam can be expelled through cracks in the rock. Hydromedusae have a variety of functions, including transporting minerals, gas production, and energy generation from the heat produced by the vent.
