Seamounts are underwater mountains formed by volcanic activity. They rise from the ocean floor but do not reach the water's surface. These geological features can vary in height and shape, and they often create unique habitats for marine life. Many seamounts are found in groups, known as seamount chains, and they play a crucial role in ocean ecosystems. The surrounding waters are often rich in nutrients, attracting diverse species such as fish, corals, and other marine organisms. Seamounts are important for biodiversity and can also be sites for fishing and scientific research.
