	Various bacteria live on Vailulu'u, including in microbial mats on basalts, which are related to bacteria from Tangaroa Seamount in the Kermadec Ridge, Loihi in Hawaii and in the East Pacific Rise. A number of mostly pigmented yeasts and other fungi have been identified in deposits from the Nafanua Cone and in iron mats and might play important roles in the ecosystems of Vailulu'u.
