There are about 100.000 seamounts over 1 kilometer around the sea. We don't know much about it because the journey to see it is longer and difficult. The upper parts of seamounts are perfect places for sea life. Las Gemelas is a place located 500 kilometers from the coast of Costa Rica. A group of cientists travelled there to see the botton of these mountains and explore it.
