The Túnel de la Atlántida (Lanzarote, Spain) is the largest submerged lava tube in the world, with about 2000 m of development and a maximum depth of 63 m. It is home to a special anchialine ecosystem with more than 30 endemic species. In recent years a team of researchers led by the UNED has conducted several geological studies to understand the paleo-environmental evolution of this peculiar underwater ecosystem, reconstructing its evolution since it was formed about 20,000 years ago to the present.
