Seamounts are underwater mountains home to cold-water coral reeds and sponge grounds. The nutrient rich waters around the seamounts are abundant with plankton and are used as feeding stations for travelling sharks, fish and whales. There are four primary named seamounts in Tristan’s waters: Crawford, Yakhont, RSA and McNish. There are others yet to be explored.
