Scientists have discovered animal communities such as tube worms and snails living in underwater volcanic caves, previously unknown ecosystems.
Four new species of worms have been discovered on the deep sea by submarines and remote-controlled diving equipment from the University of California San Diego, USA (UCSD).
The new underwater map reveals towering towers and hydrothermal vents rising from the sea floor in the dark off the Pacific Northwest.

The Rio Tinto River, Devon Island, Kilauea volcano, are three of the places on Earth that resemble planets and moons in the solar system.

Hydrothermal vents and the first chemical reactions on the ocean floor are the cause of the first life on Earth.
This area of hydrothermal vents is located deep west of the North Atlantic, far from the solar energy that helps sustain life.
About 35km north of Inukjuak - an Inuit village in northern Quebec - about 35km there is an unusually rising rock strip from the ground.
