Geothermal Vents

Openings in the Earth's surface from which heated water and gases are discharged, often found in areas with volcanic activity, contributing to diverse ecosystems in the deep sea.

Tidal Flats

Broad, flat areas of land alternately covered and exposed by the rise and fall of tides, rich in biodiversity and important ecologically.

Astrobiologists

Scientists who study the possibility of life beyond Earth, investigating conditions that support life in the universe.

Extreme Habitats

Environments where conditions are considered extreme or harsh for most forms of life, such as deep-sea vents or arctic tundra.
